THE TRUTH ABOUT GLOFISH | Glofish Explained 

I don't think it's cruel to own them, it's better to give them a good life. Instead of constantly living in a bad tank.

“I should do another video about Walmart and fish” the shade is a total mood I cried 😂

i hate it when people get upset against gmo animals or fish. i mean 75% of our current domestic animals have some sort of gmo in them.

“The state of California initially balked at the idea of transgenic fish, but in 2015 reversed course and allowed aquarium owners to buy and keep them.” For those in Cali commenting years after this video was uploaded.

Umm there are lots of glofish in california

The problem I have with glo fish is they shouldn't be kept under a blacklight. They need sunlight from a regular bulb. Blacklight use should be limited for the night time.

She does explain about the ones banned in places are the 'painted' 'tattooed' fish. injected with paint. Those are NOT GloFish.

Who just came to the comments😂

While glofish are gmo, they are not a problem considering escaped pets will soon be eaten because they look like swimming highlighters

love feeding my glofish! They're fun to watch and move fast, (especially when they see me walk in the room) I agree that they should be in a decent size tank.

Not in Cali!?? Then what are they selling us . . . Must be glow plastic

I'm not keen, I personally think the fish are pretty enough as they are. They're not toys.

I just hate the over breeding part, look what it has done to dogs for example! So many dog breeds are so overbreeded that they have all kinds of health issues, I just hope they don't do that to fish as well. Personally I like the natural version of fish (and other animals) better.

We recently bought a tank off Craigslist, I'm so glad you had posted your nitrogen cycle video, it helped so much with getting the tank established again! The tank we purchased included 2 Glo Fish. I personally wouldn't have purchased them, but our family tries to avoid GMOs, plus I'm just not a huge fan of the look. Love these videos! They're always so informative and well done!!

Just wanted to let you know you kept saying black lights. black lights are actually really bad for us to look at especially young kids and the fish. So what most of the tanks have on them are blue lights. Like the ones you find on saltwater tanks.

I have 3 tiger barbs and 10 tetras glofish. - And then 6 white tetras in a 30 gallon tank and its so cool i love feeding them and just watching them swim

That was well done, explained in detail I believe. As benign as they may be I enjoy the fish most often worked on in their natural state, not even the long fin varieties of any aquarium fish, and try to replicate their surroundings in as natural a state as possible. I had no idea of the glofish monopoly that includes their proprietary tanks which are as bad for the fish keeping industry as,say, feeder goldfish. In my mind there are some things best left natural, this is not being done for a cure for cancer, simply a selling attraction.

Babies are born with colors I been breeding glow fish for years they always keep the nice colors

Got 6 glofish in a 20 gallon. I love them tbh

I don't think there's any difference between glofish and goldfish. Both are unnatural color morphs often marketed for tiny tanks and bowls that are usually obtained for children. Too bad there are so few people who will actually appreciate them in larger, healthier tanks.

First of all, no different than mixing dog breeds, also i do not recommend anything under a 10 gallon tank. Smaller tanks are actually harder to take care of. Like she says they are schooling fish at least 5, again only danios will work in a 10 gallon. I have a 29 gallon tank with 10 barb 4 peppered cory and 1 female betta and they are chilling. Filtration is KEY, I have a 10 gallon tank with 4 danio and 3 platy, with a filter rated for 70 gallons! Makes my like waaaaaaaay easier same size filter in the 29 gallon. You can NEVER have too much filtration! Buy the biggest and best filter you can afford! Glofish are cool, enjoy!

I inherited 4 glofish tetras in a 5 gallon tank along with 5 neons and 2 zebras. i moved them to a 10 gallon where they are much happier. i find the GMO thing a bit freaky but I am loving having them all the same. They are gorgeous fish, very lively, and get on with their tank mates very well. They were very stressed and snippy in the 5 gallon. They are fairly territorial with each other and have their own little hangout spots in the tank, but pay no mind to the other fish.

I agree, people don't seem to understand that Glofish are simply white Tetras or Zebra Danios that are injected with a color/glow gene from a jellyfish and to my knowledge they don't even do that once they develop several generations of breeding pairs, they simply breed glowfish and keep perpetuating them. Personally I love Glofish as I like colors that pop (something that is sorely lacking in the freshwater variety IMHO). I have a 10 gallon kit at my work and a few videos posted of it. I have a few of Glofish and they have been doing well for several months months now.

Thankyou Heidi for clearing it up for everyone. I was once confused about the Glofish but now it all makes sense.

Any fish that is man made and commercially bred I am all for, it means less fish taken from the wild.

Painted glass fish! That's a blast from the past, I had a 20 gal full of those when I was a kid.

Great info Heidi, especially about the unfortunate practice of companies/store chains that push ultra small tanks for fish that do best in numbers with some horizontal space.

I really wish they had nano glofish. Glofish micro rasboras would look amazing and sell amazingly. Or possibly glofish endlers. I would buy the heck out of those.

I have a 5.5 gallon tank and I'm getting some glofish. Any tips for keeping them, I think its okay to breed fish with different things AS LONG AS you aren't dying them or painting the fish.

There are glow fish in California!!!😋

i personally love glofish, i had 5 glofish danios in my 10 gallon tank (no blacklight however) but i found that my yellow and green ones survived more than my pinks ones, the pink ones would always die; my two yellow and one green outlived five pinks

I'm from California and we do have glofish

i have a moonrise pink glofish, and it is so calm! i call mine, “bubbles”, and she/he stares at themselves all the time haha. i keep bubbles with another tropical fish, i’m not sure what it’s called, but it’s small and they actually get along very well. anyways, thank you for sharing this information for starters that get glofish! :)

I'm the extreme opposite of anything GMO, am a Permaculturalist, work at a Co-op, and a vegetarian. GMO's are like the dark evil NWO to me. But my friend brought me a green tetra Glofish... and I have to admit this little green dude is pretty dope. With that said screw GMO's but Glofish are dope.

Yeah I own a 10 gallon Glofish tank and I was only allowed one fish every week until I got three. (First time with fish.) He was a green Skirted Tetra and he wouldn’t really eat or swim around. Then when we got the other two he got really excited and started being normal and started eating, so yeah that was good.

They are beautiful ,and colorful freshwater fish...back in the day , you had to go saltwater to get those vibrant colors ...I just want to get my purple tetra get along with my yellow one!

My yellow glo fish killed 4 neon tetra overnight. Bit pieces out of them. Murderer.

I just bought two glofish today, both are supposed to be red but one of them is a lil brighter than the other more like pink if anything so I named it pinky :) the other is named Ali G.

Thank you for explaining things. I was really curious and it was far more entertaining to do other things while you broke this down. I still thought glofish were physically dyed.

Great vid, learned some new info from you, thanks!

wow now i just feel plain awful, i got a 1.5 gallon tank with 3 danio glofish and knowing its not big enough.... really sucks and breaks my heart and also that i might not have gotten enough of them to feel safe....... in a few weeks on the 17th when i get my next paycheck, ill be going back to the pet store and getting the 20 gallon tank, let the tank cycle for a week or two and then switching them over ASAP!!! somehow i had a gut feeling i should of gotten the 20 gallon... really nice video!! very informative, and this is my first time taking care of fish, and next time i wont listen to the pet store employees, i did want a smaller tank to save a bit on space, so probably my own fault for trying to be cheap and save on space... they assured me that a 1.5 gallon tank was big enough for 3 danio glofish, so far i havent seen them act aggresive towards one another, ill be watchng very closely until i can get them in the bigger tank! ...... should of done my own research first!!

I have a 10 gallon with glofish. Tiger Barbs, Danios and Tetras. 2 of each. I also have an albino cori dora and albino pleco in the same tank. The maintenance is easy and they all seem to do well in there together. I have lots of glowing plants for them to hide in and it looks great. I suggest the glofish cycle plants and cycle lights that change with white, blue and black light. Very cool setup for my home office. I would like a bigger tank and few more fish, but there is not enough room at the moment for all that.

I want to have an octopus sometimes.

the lady at the fish store assured me I could by 3 and put in a 5-gallon tank so I did today..... ugh I asked her if it's for sure ok...

How many Glofish can I put in a 5 gallon tank ?

Where are your sources?

I was thinking of getting a 125 gallon tank n putting 60 different kinds of glowfish in there

Love your videos! Good explanation of some VERY misunderstood fish.

Madam I want to keep glow fish but in my area ambient temp go max 50 C and now a days my tank water temp is 34 C here fan not work as they throw hot air and water temp increase so I try to arrange chiller or can I keep glow in 34 or 35 C without chiller.

55 and I luv glo fish especially @ night under the pale blue moonlight !

You said they do best in larger groups? I was going to get a 20 gallon tank with like 5 because they are $10 a peice. Is that not enough. And will they breed? If not, why?

They came out with glofish rainbow sharks oh no

Hey! I have a GloFish tetra. I have a few questions and have been researching all night and finding no answers. Is there any way to contact you?

I have a 32.5-gallon tank with a 1-Betta, 5-Glo -Tetras, 6-glo-Danios & 2-Power Blue Gourami. They get along great, rapidly swim all over the tank and none of them really get around the Betta, who is in his own world.

I spent $200 to make sure my glofish live the best life I’m going to get them tommorow I pre-set up the tank to let the tank filter and clean out and I got plenty of hide holes and plants for them to have and I got the nicest tank at my local pet store it was high priced but I want my fish to live a good life,I cleaned all the decor and gravel..

The barbs are really cool looking, but they don't seem to be nearly as healthy as the regular tiger barbs.

I’ve owned many glo fish my glo fish have lived a long time and no color fading or anything like that I turn the black light on at night and regular light all day yes they are colorful I got them because there so cute and small not all bout color there fine I do regular cleaning along with a pleco fish yes it’s messed up they are painted of etc but I do believe every kind of animal needs a home

Thank you Michael McCarthy for posting your comment, if you haven't done so, you should post a video about this "said corporate end" to the hobby. Very soon someone will come over to your home and take a look at your freshwater aquarium and all you'll hear is... hey do you have glow fish? how come you don't have glow fish? On a another note if someone was to come over my place and check out my marine aquarium, notices my Royal Gramma and ask.. is that a glow fish, I've never seen a glow fish like that before? I would totally lose my cool and Snap! Everybody please read Mr. McCarthy comment he really does a good job explaining this... well I'm calling it an issue!

Mann I love my glofish. I have 9 glo fish tetras and one black molly in a 10-gallon vertical tank

I personally don’t care that much for them. I don’t like the way they’re displayed in pet stores and I don’t think it’s right for a fish to live pretty much their entire life under a black light for some kids amusement. Let’s be honest these are marketed toward kids who have an attention span of most gold fish. So when they loose interest most aren’t gonna be returned back to the store. Most are gonna get flushed or set into the wild and I don’t think that’s fair to them or any fish for that matter. I just don’t like the idea of creating a fish under the microscope then putting them in the hands of these young children and not knowing if they are released into the wild what kind of effect they would have on the ecosystems they’d be released into. These are hardy fish that can live in not so favorable conditions so imagine going fishing and catching a 10 ft glowing tiger barb in somebody’s lake lol it’s bad enough we’re out here eating tilapia when ten years ago I’m pretty sure they didn’t exist.

We had some of those glass fish back when I was a kid..... they were awful aggressive things that killed a heap of our community tank. The dye did fade, but most of them died before that happened.

Golfish are developed as a product. The thing that crosses my mind is, while they aren’t being dyed, how many fish suffer in the development of the Glofish? This isn’t even to mention how many will suffer as a result of being bought by people who know nothing about fish keeping and the nitrogen cycle. I believe anyone who wants to keep fish should have to take classes and become certified to own them.

Hey. Thanks so much for making this video! I wish I had seen it before buying the 5.5 gallon "glotank" for my 8 year old daughter as her first pet. But anyway, it's currently cycling with an aquatic plant and a nerite snail. I think we're almost ready for the fish, so how many should I get since they need to be schooled? If I get different types (danio, tiger, and tetra) will they not school? Should we pick one type?

I am about to buy glofish for my daughter. I have a 10 gallon tank and plan to have 6. I also am going to upgrade the tank in a year (is that too long)? Or should I upgrade it before then? I AM NEW TO THIS WHOLE FISH/ GLOFISH THING AND AM RESEARCHING AS MUCH I CAN. WE ARE GETTING OUR FIRST TWO GLOFISH TOMORROW (provided the water text goes well).

We just got a 5 gal glotank with 3 glofish. Should we purchase more to prevent discomfort for them?

I have 2 glofish that was given to me many months ago by a guy who came into my work. Never kept them before. He said that if I didn't take them, then he was going to flush them. A pretty pink, and a pretty purple one. Well I had no where to put them except my goldfish tank. Well it's now may and they are thriving. I live in a state where it's never cold so a heater isn't needed. I am about to move the goldfish into the pond so it will be just them. I love glofish.

I have 4 goodish tetras in my 10 gallon and I want one more but would that overcrowd my tank? My existing fish have been in the tank for over a year and sort of leave each other alone. I see them chase one another very rarely and they never hurt each other. I'm wondering if one or even two more tetras would make them more social and happier, or if it would mess up the hierarchy my fish already have. I have no idea and I want at least one more fish because mine tend to hide about half the time and I want them to school. Any advice?

Bought a green large glofish and I think he killed the 2 smaller pink ones. He had a solo freak out earlier, where he like was trying to escape, racing and pacing. Then he went into the bottom corner with hos head down for 20 minutes. A few hours later, he seems back to normal but the 2 smaller pink ones are dead.

When I first encountered glofish, I'll admit I was immediately wary that they had been dyed. As colorful as fish can be, these guys simply don't look natural, especially after seeing their non-glo counterparts. I stay away from them out of preference/principle. When my sister and I were kids, we loved color just like any other - we started with a red veiltail betta named Lipstick and a small school of 6 assorted guppies. It was a huge lesson in fishkeeping and big accomplishment to us kids when our guppies were content enough to start spawning. We quickly learned how to rear the fry and sex/separate the adults, lol

I have two long fin glowfish and they keep fighting. I have to keep putting them in time out. It's helping a little cause I keep watching to see who is starting the fight. -.- so annoying cause its tiring.

I have glofish. Wondering what I should change? I have 3 glofish and 2 dalmatian mollies in a 10gal.

Tons of these out in California - Along with the aquarium kits.....Certainly not for me, but, maybe they provide some value in getting kids interested in the hobby 😀 I don't have any experience with them, but I have to imagine they only live a year or two....similar to other people who experiment with breeding and fish coloration, the process can shorten their life span. That being said, if I had a 10 year old daughter and she wanted glofish....I'd be on my way to the store right now to buy a glofish tank 😉

Hi Heidi, I just set up a 75 gallon for community fish. I saw Glow Fish for the first time while doing this. I did my research on community fish.Thanks for educating me further. I am retired and am fascinated with fish. My question is this. If Tetra Barbs are docile with non- aggressive fish, why are they separated in stores from, let’s say friendly fish and aggressive?

My glofish are healthy and they’re eating properly and I’ve given them an aquarium with multiple glow in the dark plants and a cave and rocks along with a filter and a very small bubble machine. But their activity is very low most of the time and I’m not sure if it’s because they’re each a different color of glofish or maybe the tank isn’t big enough? It’s really worrying me and I could use some help

I have Glofish in with my Platys. So far so good. I just spotted 3 platys babies yesterday. Will the Glofish eat them? I hope not. I have 6 Glofish and 7 platys in my 20 gallon. Is that sufficient space for that many fish? I’ve set up the tank about 2 mos ago

White skirts are NOT albino, thus do not have weaker genes. The glofish 5 gallon tank is more than suitable for a school of glo danios. The Glofish tanks don't use black light, it's blue LED.

Hi i got a 10 gallons glow tank- and some rocks because they said sand will not work with them! Because the filter - anyways what do feed them how do i set this tank up and how many fish do i need for a 10 gallon

Hi not sure if you could help me out with information.. I have a blue and yellow GloFish in a tank with a guppy. One day while cleaning the tank I found one little baby fish. It survived and is doing great. Only thing is he is white... his body is the same as my other GloFish but he is white not a color. He’s not fully grown yet but just wondering if this is normal?

My glofish has been living for 2 years so far

I have a 40gallon and and 20gallon..the 20gallon was my kids and they had 9 glofish tetra. Well under my husbands supervision 8 died...they were being overfeed. So I completely took down their tank and put survivor fish in my 40. So now what tank mates can be with lil survivor?

My parents have a huge tank with about 6 or 7 glofish tetras. I personally don’t like them because the bright color is kinda ugly idk I like natural color better. Anyway so one of them has these big white spots on them and I don’t that it’s ich/whitespot because the spots are bigger and kind of look like they are under the skin. Can someone please explain? I really want to make sure these fish stay healthy and happy

I wish she would post more!!!

I had danios and unfortunately my bigger one was extremely aggressive and attacked my mellow guy. They ended up ending each other 😞😞😞

It's still terrible and cruel to do that to a fish. Not only that people get the misperception of keeping them under a black light all the time. WAKE UP PEOPLE they are still regular fish they need light.

GloFish is cruel for marketing GloFish without highlighting that they need to be schooled with 5 or more Glow fish... Marketing a 5 gal tanks encourages overstocking or building less than 5

I have a 50 gallon tank (with GloFish) They don’t even make attachable black lights for aquariums of that size so we had to figure out how to put them in the tank to work properly. Thankfully, we figured it out, but come on! Not only can you only find little tanks, but you can’t even buy a large tank and add a black light to it without drilling holes or duct tape (please don’t do duct tape)

I put two in a 240 that otherwise is a naturalistic design. For one thing I have small shoals of Bleeding Hearts and Colombian Tetra's so the glo black tetras that are near pink...sort of fit in. Just the most colorful of the lot. I avoided the long fins since I thought they might be nipped by other fish. Already the two are intershoaling with the other tanks fish. Rainbows and more.

I have a 10 gallon GloFish aquarium how many glofish you consider a good amount for a school type so they won’t become aggressive or start picking each other’s?

Glofish are now legal in California just an FYI. I’ve been seeing them at pet stores the past few months.

very informative, sources in the info box would be appreciated!

if i buy 4 tetra glow fish, will that be okay? and if so how big of a tank?

If you're not going to show us the fish, I'm not going to waste my time watching this.

I have a blue and purple Glofish with my Black Skirt Tetra and they do well. I also don’t use the black light.

God bless you I did not know this till now because I was going to purchase glofish but now I will not thanks to you !! Now I know what I didn't know thank you very much !!!

I have a school of glofish in my 30 gallon tank and they’re just fine, I’m 16 so I didn’t just buy them for my kids amusement haha

Great vid... you got a new subscriber! I usually only sub the heavies (Joey etc.) I appreciate dispelling the rumors, i was around back when they tatted fidh and i HATED them.

Your really pretty why you keep playing with your hair. Great video thanks for the info 😊

In Dallas Texas I have 11 in a 10 gallon and 7 in a 30 gallon with 20 b.aires tetras the ones in the 30 gallon do great 👍 but the 11 in the 10 gallon over 6 months have began to pick at each other as they get bigger may have to take some out

Can they stay with goldfish??? I have glo purple tetra fish.

Great video but stop touching your bangs!! Lol
