My fry are about a week old now, some of them have really grown and look like week olds, others are still smaller. My question is, A LOT of them hang around the bottom of the tank where I put the microworms. It looks like they're laying there dead, but occassionally some will swim up from the bottom and i'll see some swim down and just lay there like the others.
But, today I took a turkey baster and blew some air/water in the area just to make sure they were still alive, I couldn't tell if some of them were dead or not.
Now I am concerned because if a good number of them are actually dead, I don't just want to leave their decomposing bodies in there to polute the tank and if they ARE NOT dead and I siphon them out, then I WILL kill them.
So I would like to know...is it normal for fry to hang out on the bottom of the tank and hardly move and how can I be certain whether the fish are actually dead or feeding??
