I found a bunch of daphnia in a puddle on the ATV trail near my work. I've now taken my old 10 gallon and some greenwater from my 30 gallon to make a mini culture tank... My hope is the lights and empty tank will boost that greenwater algae as fast as the daphnia spawn and create an infinity tank of sorts, but i'm also gonna use some of this advice to go even further beyond! The only question is if i should add a bubbler to give it airation or keep it stillwater like the puddle i found them in....
In this method the daphnia would mainly reproduce by cloning themselves and giving live birth. If conditions become unfavorable for them (which maynot in this situation as he feeding greenwater and doing water changes) they will then produce males and females and they will mate producing egg sacs. Youll see it in females as a tiny dark color pea shaped sac on their back. They would them release them and you can see some floating in water surface but majority would be in the debris in the tub base. Siphon it out using a bbs net and then air dry until completely dry. Store in air tight container to use at later date. Hope this helps.
Interesting! May try my hand at a much smaller scale setup. I can usually collect a bunch of daphnia at local pond as a starter culture. Unsure about green water culture. 🤔 Thanks for sharing.
They say daphnia is easy to breed, but was not so for me. I bought a culture and they died within a week. I kept them in a big bowl without air pump, and fed them regularly. I don't know is it the lack of air pump that killed them
Did you culture for only free floating Alge in your starter? I only ask because when I selected for only the free floating Alge I never got any hairy Alge ever.
Hair algae can appear in daphnia tubs that have been culturing for several months. You only want free floating algae as the hair or string algae can't be used as food for them and they can get entangled/trapped causing them to die.
Some dry cow patties powdered up and wet thoughouly. And crushed egg shell works great. I use containers of water outside for mosquitos too. Their larvae is good free food.
What do you mean algae grow along the filament one, you need to start a new culture? Sorry, I didn’t quite understand what you meant there. Thank you for the education on daphnia.
If you get the long thread like algae, you want to start over. It interferes with their ability to swim easily. If you get it you will know....if not, no need to worry!
Growing Zone 7b. The daphnia barely produce anything second half of december until late February when you have some warm weeks. But they will survive (or at least their eggs do). In summer, it gets so hot that I keep them shaded.
Will the eggs hatch if you move the mop to another tank, without using the peat moss and dish? Just curious if they will hatch it water without intervention. Thanks new sub 🎉
they will cuz theyre not annunal killifishes which means their eggs can incubate in the water, and will incubate a lot faster in the water vs moist peat
Hey Michael. Daniel from Denmark here... The peat, do you have a link for those? I am really impressed with how you did that. I recently bought 5 different kinds of killi eggs. Do you sell those?
So I buy Jiffy #7 Tabs off amazon. I've used peat from the hardware store in the past but it requires boiling to make it sink. The tabs sink within 5 minutes after placing in water.
@@michaelecht2216 Thanks for the answer. I just got two pairs on the 4th of January. They are already spawning. They couldn't wait until they came to the "foreverhome". Have you any experience with letting the eggs hatch without taking them out, It is also worth mentioning that I have ramshorn snails. I am trying to get them out by hard-picking them. I see people report that they could I eggs. I had some peat for gardening I used instead. It worked out pretty well :) And thanks for the answer :)
I hope you can help me...I live in Las Vegas and have a 1000-gallon pond in my yard. I went to a nursery that sells plants for ponds and a decent sized tub with plants was also teaming with Blue Tail Killifish. They didn't know how the fish got there but suspected the plants had eggs already attached. They were nice enough to scope out 25 of these fish and give them to me at no charge! They are thriving in my pond and even hatching fry which is pretty exciting! My question to you or anyone out there is: Will my Killifish survive the cold Las Vegas winter? the temps in LV during Dec-Feb can get as low as 50 degrees and 36 degrees over night. I would hate to lose these little guys as I have become somewhat attached to them!

So this species has a few different colors depending on where they were collected. The first one is the Loe location from Cameroon and the second is the Niger Delta location from Nigeria.
Yeah Jim, that’s my fishroom with all the fish I brought back! No losses with the fish I collected, but a few losses with fish I purchased from the wholesaler…. Maybe 5%.
