do anybody else's ottos eat the flake food they put in? yesterday i actually watched my fish eat which i hadn't done in a while and i noticed that the ottos were going just as crazy swimming around looking for flakes as the other fish and they were actually gobbling them up when they found some. it just really surprised me i'd never seen them do that before. and is it true that they like groups? i know ive read that but they never seem to hang out with each other.
