When I was browsing a local exotic pet store and talking with the owner about stuff he gets out in QT he told me about how one time he had a large shipment of live rock and smaller fish in his big QT tank in the back, only for a lot of the fish to start disappearing shortly after everything was starting to get settled in the QT. Apparently somehow a smaller mantis shrimp got in and was going to town on everything it crossed paths with. Absolutely brutal, those things and bobbit worms are the stuff of nightmares.
One man's pest is another man's treasure.. ;) I think the sea spiders are incredibly cool, so I've just put 10+ of them in my cold water tank! They are a hungry bunch, but as long as they got hydroids to munch on, they seem happy enough!
I have been in the hobby for 5 years and I have managed to somehow completely avoid pests! I know my luck will run out sooner or later, living the dream until then (with proper dipping and quarantine of course)
Nudibranchs seem to need extra time in a dip to kill! What has worked for me is 1. Dipping 2. Manual removal! Use tweezers and really look hard using bright light and even magnifying glasses. 3. Remove eggs!!!! This is the most important step. Do this every week for a few weeks and then again a couple weeks after that just to check again. Then AGAIN in a month. I've wiped mine out this way and never saw them again.
The way you make monti nudis sound like the black plague is very interesting to me, I work at a store where we bring in lots of maricultired corals and we just so managed to get MEN's I was the one to discover them, just like every other pest because I sit there and stare at our corals during downtime. Using 3 tanks other than the tank discovered in and a dip in-between each tank 1 week apart then once into the final tank we filled it with bullseye mandarins and six line and yellow Coris wrasse we were able to beat it completely
I totally agree about the montipora eating nudibranches. I've tried maybe 4-5 different types of dips, all of them helped eradicate the nudibranches, but in few days the eggs hatched and they reappeared. Only after throwing all of the brown montipora corals and leaving a small piece of green montipora I was able to eradicate the infestation. It took me around 6 months of effort.
@@jmsreef850 yes smaller lol my first salt water tank was 9 years ago it was a 220 gal tank, that tank was fresh water 4 years before that (African cichlids) i sold it 6 years ago, got a very very good offer for it... Then i bought a 250gal tank again African cichlids still have it, BUT! My uncle offerd me is tank for free he left the hobby, couldn't say no lol the tank is 400gal lol L90" H32" W32", i was thinking that this is a good chance to get back to salty tank, a lot has change in those 6 years so im doing a lot of research, and it's going to be expensive lol
@@eliavedri7876 BTW, did the guy from video forgot to say which predator feeds on the most harmful #1 pest? The best would be to introduce a lot of predators so they would east the harmful things.
@@StrangerHappened Yes, there are fish that can help in some cases, it is important to combine fish, invertebrates and so... that are not only there because they are beautiful, because they have a certain important role.
Definitely start with a smaller tank, I kind of regret geting a 55 gallon tank. Wish I would of got a 20 or 25 gallon. People say bigger is better and it is... If you're lazy... What I would give to be able to do 50% water changes every week and not have to worry about anything lol. Plus then you have a quarantine tank when you do eventually upgrade.
I had a Mantis come in with a clam once, easy to get rid of, the worst was a bobbit worm, wiped out everything in my nano, my wrasse, goby, fanworms, you name it...oh and flippin aptasia, Berghia were purchased and disappeared for all time, never to be seen again, and yet, here I go trying again over in the UK with a new nano!!!
Tried the potassium permanganate bath for the monti nudibranchs. Removed all montipora colonies and dipped them for an hour in the PP solution. It did eradicate all the nudibranchs and their eggs but it was very stressful to the already stressed montis. The red monti cap is slowly bouncing back but the green monti cap seems to have dumped all its green colored zooxanthellae and taken on some of the red montis zooxanthellae as it is now turning to a pink/red color. It will be interesting to see if it can bounce fully back but as a new color.
That Bobbit worm you mentioned sends chills up my spine. I hope I never cross paths with the liking of them. Bubble algae are the biggest pain. I've been fighting an infestation for almost 3 months now and they just won't go away. Any tips? I do manual removal and I have hermit and Emerald crabs that are helpings, but at the end of the day they turn to eating whatever is left of the fish feed.
I agree, the monti eating nudibranches are pretty bad. Probably the one I worry about the most. If I see them or any type of nudibranch that is considered a pest, I go for freshwater dips. It's harsh, but it works. The way I see it, if the coral doesn't make it, then it wasn't going to make it any other way.
I found out about zoanthid eating nudibranchs the hard way. Then I dipped my colonies and bought a yellow Coris wrasse. Haven't seen any since, and the zoanthids so far (knock wood) look good.
If you let the coral slime for a certain amount of time in the atmosphere before the dip sometimes it helps reading some more of the pests and their eggs during set dip
I recently purchased a jewelry loupe magnifier (60x & 30x with led light $10 on Amazon) i got to try it out on some newly acquired Acropora frags. ..I had to take the Frag out of the water to scope it, and on one of them I managed to spot 2 red bugs. Man they’re small..and without the loupe there’s no way I would’ve seen them. The good news is that contrary to what Than said about them being resistant to commercial dips...these ones came right off after just a minute in Revive.
Lol i got some live rock from petco, brought it home and rinsed it thoroughly. Quarantined it for a while. Finally put it in my tanks and guess what? Random bristle worms that are way too hardy apparently survived and i found 2 😂 ah well
I was 4 years into a mixed 120 reef ready, I had 28 species of zoas , quite a few acros , basically a LPS and SPS to that took a battle up hill to establish. I fought a long hard battle to get rid of Nudibranchs but I did succeed. I was down to 1 premier coral store that I fully trusted and supported me fully. They got a rare zoanthid colony and I had to have some. Nope, not what your thinking, my dumb azz didn’t have a quarantine tank didn’t realize I was out of dip, so what should I do? I trusted they did their work at the store, little did I know it was a wild colony. I woke up the next day with a front glass cover in spaghetti stringy worm things (DINOFLAGELLATES) I tried every known cure, 3days of darkness , 100% water change , i am a old school aquarium guy , I even use a Vortex Diatom filter. Nothing worked. So I did the unthinkable , old school remedy, Half gallon of bleach to sump and cover tank for 48 hours. The 1st pass I didn’t lose anything of extreme value , and corals rebounded in a week. Thought I was free and clear and left lights on over night. The next morning I had more spaghetti than Luigi in Mario brothers. At this point all,was lost, I did 1 more bleaching and watched $7000 worth of coral and 4 years of stress melt to oblivion. It’s been 10 years now and though I miss my tank , I look at the prices of frags now. You can have the damn hobby. I had cichlids for almost 33 years. Should have never left them
When I first got my tank, I noticed a white aphasia on one of my live rocks, it hasn’t moved or done anything so I’m just going to keep it there. Hasn’t moved in atleast 3 years
At 11:42 what are those white little egg things moving? Are those harmful because i have them in my reef and been noticing some of my zoas disappearing. Please respond because i haven't found any info about them till i was your video.
Buddy quick question lifted a few 5inch frag rocks full of mushroom I have switched to San tmc eco from glass bottom wen l looked underneath there like bright red jelly like tenticles things under I know its not aptasia I just got rid of that wiv nudiz it was like feathery but bright red jelly and tubes made out of sand like a cadis larvy any ideas just toothbrushes them off with vinigar out of the tank in kitchen thank
All the more reason for purchasing aqua cultured corals. I’ve just found 4 flatworms, haven’t added anything to the tank for a long while, so don’t know where they’ve come from!
great information and at the same time can give you one anxiety. hahahahaa. Press LIKE button ----if youre one of those after seeing the video went to their tanks to check if such critters are present.
Levanmasol is used alot to deworm fish by putting it in their food. Its heavy duty stuff. Are these red bugs crustaceans or worms? Would shrimp eat them, since certain cleaner shrimp will actually eat parasites off coral and fish? Also what about temperature control? With certain freshwater parasites raising or lowering the temps to certain extremes can "Assist" in eradicating the parasites while only stressing the host. Has anything every been done with this in marine, with things like the spiders or slugs? Im just getting into marine from fresh so I find this interesting.
Angelfish can eat nudibranchs just wondering would be a good choice to keep that pest in checked also what would eat the spider pest thanks keep the videos going i am learning so much from them
Great video! My worst has to be digitate hydroids! After 20 years in the hobby i started an acropora focussed tank. Unfortunately the hydroids made it into my system and multiplied immensely in a short timespan. They brush up against the acro’s causing them to get an exposed spot. Lots of times this leads to a weak colony susceptible to rtn/stn. I’ve no idea how to deal with them and feel like breaking down the tank if i cant solve this problem. Any tips?
thanks for another great video.... i have a question if possible, my green montypora started fading color and turning gray... at first i tough the problem was lower level of potassium ... but now i wander ... can it be bug number 5 :( :( .... i use zeovit all the way... but just yesterday i know they advise de addition of k-balance to keep the potassium at good level. Thanks amazing video as always
ill be starting several types of tanks soon after i move. A nudibranch tank (1) a coral reef (2) and food breeding tanks for the things i can aquaculture for my aquariums. so i was just wondering
well this is good to know i just started a tank and one of these aptasia i know im butchering the name but one of them came in on my live rock that i bought
Caught a bristle worm from a favia plug checking out an empty hermit shell, luckily he did what I thought and hid in the shell when I disturbed the area and promptly removed the shell. I know they aren't bad, but look terrible!!!
I really wish you would do a video on Vermetid snails. I recently had 1 head on my frogspawn shrink to almost nothing then I noticed a vermetid on it..... I removed the snail and the head has recovered almost fully. I cannot find much info on this pest and I'm sure you have the knowledge! you rock Than
my tank is 25 gal and been set up for almost 4 month and I just bought a yellow tang and the litte guy survive only for like a week and then he die brown spot appear on the skin is that because my tank is only 4 month old or is because I have those brown algea on my tank
+juan sanchez first thing.. dont put a yellow tang in a 25g tank... not to be the tang police, but anything smaller than 55 is too small for even the SMALL species of tangs.
No hard corals for me!! I would freak out seeing any type of bug. I am not new to fish keeping, but I AM new to the saltwater hobby. Just watching this has me itching. ewwwwww
I like Reef Primer a lot. It is gentle on the corals and is effective against a wide range of pests. No dip is perfect, but I favor the ones that do not stress the corals as much.
I have a long big white flat - worm, just discovered it, trying to figure out what it is and how to remove. I don't have any corals but I plan on getting some. I also have aiptasia and bristle worms. All in one rock.
+Bob Gregor I put it in freshwater for a week and then dried it out and then added it to a bucket of saltwater (so that when I put it back into the aquarium the ammonia won't spike) going to add it back in this weekend. Thanks for the advice though! :)
We got some red Goni eating nudibranchs once, they were SO hard to get rid of. Also, what's your opinion on medusa worms? They're the worst pest I have in my tank and by far the most annoying
I have an established bio cube with mostly lps I’ve just noticed what look like thin while hair like worms coming up from my sand bed. Not sure if pest or benign
+RavineDriver Bayer is not good for soft corals or corals with soft tissue (euphyilla etc.).It can burn it right up if you use a dose to kill pests. I use Bayer for all my SPS and chalices as it is just about the only thing that will kill AEFW. It does cause tissue necrosis, but I'd much rather lose one piece rather than get my system infected. I recommend ME Coral dip instead of Revive since it came on the market. It's more concentrated and the lavender as well as the two extracts in Revive. Hope this helps.
Informative video as usual guys. Do you know much about Digitate Hydroids? I have them spreading around my tank at the moment and I'm not sure how to remove them. I've dipped the rocks, scrubbed the rocks with a toothbrush and even tried boiling RO water to no avail.
+Jordan Reid jell super glue. take rock out and drop glue on the openings of the tube. I got rid of all mine that way. Eventualy they all die off and the glue falls away. Don't pull them out, supposedly they spread faster.
+Jordan Reid please don't boil anything from the tank inside your house unless you're willing to take the chance of sending your entire family to the emergency room, or worse. Boiling the rock could vaporize some very deadly toxins. I also suggest wearing gloves, face mask, & safety goggles whenever handling certain corals. There are some real horror stories surrounding this hobby that unfortunately never seam to get talked about.

Montipora nudis easily sorted with a yellow wrasse... Aiptasia have beaten me everytime and I've tried everything. I'm on my 3rd re start due to Aiptasia...they should have been at number 1 worst pest
What is your take on Hydroid Jellyfish? I have them completely covering my glass. I scrape them off, and they land on corals, and irritate them.. They have been growing in number for about a month. Ideas?
I have the same pest. everyone who has responded to my question a about them online say they always dissapear after a while and are relatively harmless.
Am I weird for wanting to harvest nudibranchs in a completely separate tank just to observe them and watch them grow? The look somewhat beautiful although I'm glad I've never had any in my reef tanks.
I just found a white slug With blue line down the belly and Bluetip. With some where looking feathered legs and feathered antenna. Anybody know what it is?
+The Punisher no The closest thing I could find online about it is it like to eat soft stony coral. I don't remember the name but hopefully I got it out of my tank in time before it laid eggs.
Red bugs are a dream compared to AEFW. You just dose interceptor once, do some water changes and you're done. (You have to find a vet to prescribe it though) You forgot the mention the fact, if one has AEFW or nudibranch you should establish a quarantine system for corals that the pest can infest and let the tank fallow for several months. (If you have AEFW, you must relocate ALL acropora and put into a quarantine system. You have to starve out all the ones in your display tank for 3-4 months, then you can reintroduce your pest free corals back into the tank). I had to do this for AEFW, it was a nightmare.
