i agree with you michael, you cant just say,"ok he he's eating, so i dont have to worry about anything". i've just read on several types of fish 'difficult to acclimate to aquarium, but once acclimated, will do very well in aquarium'. my dot-dash butterfly, added yesterday, is very active, even continued swimming back and forth after lights out and was swimming before lights on this morning. he wants to eat, i just have to find out what he really likes. i put some frozen food(krill or clam?) that the foxface and green chomis loves. he would take some in and spit it out. i guess it just wasnt his taste. he ate some flake food and some frozen brine shrimp. i put in some seaweed select, but the pig foxybrown ate it all before the bf could finish acclimation period. also when i walk up to the tank, he hides and by the time he comes out the other fish are well on their way to eating it all. i guess when he's more comfortable he may not hide at feeding time.
