About a month ago I stocked a 90g with 10 yellow labs, 9 yellow tail acei, 9 rusties, and 8 pearl zebras. Most of the zebras and acei are are around 1.5-2 inches. Most of the labs and rusties are around 1-1.5 inches. I am worried about some of the fish not eating enough and/or dying off. In particular the smaller fish. I have already found 1 dead lab that was almost completely devoured and my count of rusties has always been at least one short. I guess one of my questions is are you supposed to tear down your tank every time you suspect a fish may be dead to take the body out? Or is it common to not find a dead fish until its been snacked on by the others? I'm hoping my fish didn't get any sickness from feeding on the dead lab. I am occasionally seeing some stringy white poop floating in the aquarium. Should I be worried about this? During feeding time most of the fish are crowding near the top of the tank but I notice a couple small labs that hide in the rocks at the bottom. I've been feeding about an 1/8th tsp of NLS cichlid pellets twice a day and this seems to keep most fish at a healthy size except some of the rusties have fat bellies and some of the labs are looking thin. Do you think I should try feeding a little more for the small labs? Thanks for the help.
