Fry take 2 fail

Hey gang, its been awhile since ive been here in the rifties section. that last batch of fry that i had from my dayglow aulonocara went well the first 21 days. i let the female hold them and than striped the fry. than i raised them in a tumbler until they were free swimming. from there i moved them into a bare 10g. once their stumachs were gone i began to powder my foods and use a turkey baster to feed them. than about 4-5 days later they started to go belly up, a few first, than slowly more and more until they were all gone idk what happened, but for the second time it didnt work.

i tried to do a partial change every other day to suck the leftover food. and i had a sponge prefilter to keep them from getting sucked in. and at day 21 they still had quite a bit of the yolk sac left, they wernt capable of swimming still so i left them on a real gentle tumble. once they could sorta swim i turned it down lower, than when they could swim i left it off and than made the move. idk, i suppose maybe i should have ordered or found some fry food rather than powdering food.

I would increase your water changes - the sponge filters don't provide much filtration. It sounds like the fry developing on the slow side, maybe due to low temps. Keep the temperature at about 80. I've had a lot of success with fragile fry on NLS fry starter powder and decapsulated bs eggs. Microworms are pretty easy to keep on hand too.

sorry, i wasnt clear on my filter. i have a HOB with 100gph with a sponge over the filter to keep them from getting sucked in.

they were developing slow and were in low 70s. i got a heater for the 10 and slowly cranked it up to like 78. next time im gonna buy specialized fry food rather than trying to make my own.

Ive been thru such on many occassions with many batches, usually due to my laziness.

Rearing tank should be monitored closely until you get the hang of it, especially in small tank.

Reasons can be many but at least avoid xtreme conditions (it could happened pretty faster than most may think) and/or sudden drastic changes.

Try Paracyprichromis nigripinnis in your avatar, a gorgeous fish.

Better luck with next spawn.

thanks, ill try to monitor the tank more next time, with finals and all coming up i didnt watch the tank as much as i should have.

and my avatar is actually Benthochromis tricoti, the tang fish that i wish to have the most, maybe someday. I've always wanted a nice group of paracyps, but ive never really had the money, and now i just dont have the time since I'll be shutting down my tanks in a few months.
