Hello! I have 4 young convict cichlids in a 55 gal and I am having trouble feeding them. More specifically, the aquarium is so large that they either don't notice or barely notice when I drop frozen brine shrimp or sinking bug bite pellets. This results in most of the food going uneaten and sinking to the aquarium floor where it seems to stay. They don't really eat it afterwards. Does anyone have any tricks on how to get these little guys to actually eat/notice that I have put food in the tank?
