Hey guys. I keep seeing something about feed your fish for two minutes and thats good. Heres the thing, only about 1/2 of the "Pellets" get eaten before they hit the botton of the tank. I started dropping them a few at a time only. Is that what they mean by feeding for two minutes? or will my fish eventually realize food is on the ground and eat that? I dont want TOO much build up on the ground, yet it seems only 1/2 the food, if that much, is getting eaten.
