why is it that new fish don't eat at first?? i've seen it many times, where they either aren't interested in eating at all- OR they act ravenous, but spit out the food for a few days. I was just curious why? I assumed stress from moving was to do with the not eating, but i totally don't get the spit out food thing. when should i become concerned if they aren't eating regularly?
also, i have a tank with top swimmers and middle swimmers, how can I be sure all are being fed (i have some barbs that feed in a frenzy, and push my danios out of the way to eat)!?
