i was wondering my new guy is about 5in and has been in the tank for 3 days he is not eating anything i put in for him he just cruises the tank like a oscar just floating around.i thought these fish where more active and have big appetites all he has ate is bloodworm and a bit of krill.he or she is pretty aggressive i had to move my red devil out now he got the tank to himself but just will not eat pellets should i feed every other day get him hungry first?
