Everytime I feed my neons some get very rounded and lumpy. Is this ok? I'm sure I'm not over feeding. I feed them 3-4 flakes crushed for their little mouths. One tetra is very greedy and is like something possessed when I feed them and she gets very lumpy indeed. It does go down after an hour or so but I'm worried they will burst!
It's probably not a serious health issue, although neons are very small and really don't need a lot of food to live. The type of flake you are feeding them may also effect things, some flake has more fiber than others
