    Hi everyone I have 1 week old Cory fry and within the last 24 hours I've had about 13 die. Some of them were my fault, but when I wake up to six new ones dead, I just don't get it. I feed them three times a day, suck up any uneaten food very well, and change a little water every other day now. I have checked the water and that's not an issue at all. I also inspected the dead fry to see if there was any signs of disease, but saw nothing. However, I did notice that it looked like there was no food on their bellies. I know I feed them enough food each time so I don't know why they wouldn't be able to get something to eat. Any ideas on what is going on or what I could possibly do to help these guys out?

    When did you start feeding them? If you start too soon before they've absorbed their egg sac their digestive system doesn't develop properly & even if they then eat they can't digest it.

    I had one from a previous spawn so there has been food in there from day one. I didn't put much in there to start with just enough for the one to eat and the others didn't go for it. I would sit there and watch him so when he was done I could suck the extra up. They all started to eat about three days after they hatched though.

    I always hatch fry in separate tubs, then when they've absorbed the egg sac & are starting to eat, if I have other fry a similar age I transfer them to that tub.
    It's possible that having food in their tub from the day they hatched is what's causing the problem or it could be just nature weeding out the weak ones.

    I hope it's just the weaker ones. I mean they are all really small compared to the others. We will see what happens, but as long as I get 10 to put in my main tank I guess I'll be happy-ish.
