ok well i feed my fish, i know im not feeding them too much, i have leftovers at the bottom of the tank. i never used to have this until i got my bigger tank, the fish just arent seeing all the food so they dont come to it. Im not sure if im not feeding them right or what? i give them one brine cube a night, which ive been doing forever, and they used to eat it all, now they cant see it so they dont eat it all and it sits at the bottom, is this normal or am i feeding wrong now that i have a larger tank. and if everything is fine, then is there something that i can get to eat all the leftover food at the bottom so it doesnt contaminate the water or anything ?
