well about a week ago while at a friends house i was looking at his tank and he has a thin layer of gravel with a non running undergravel filter. well i decided to look and see how much fish poop was under his tank so i looked under the stand and saw something swimming around under the filter, well it turns out that his last batch of convict fry(all babies died) had two strays that decided to burrow, the only two survivors of the last batch of fry were living off fish poop under the filter, so we took the tank all apart to get to them and saved them. we decided against putting the undergravel filter plates back in so as not to have any more baby fish episodes. so if you decide to have an undergravel filter, and your fish breed DO NOT have a thin layer of gravel.
