Five day's ago...I got a Carpintis cichlid (2 inches) and hes is not eating!! I tried giving him flakes,brine shrimp,bloodworms,and pellets. and he still isn't eating? The first day I got him I gave him a little bit of brine shrimp and he only ate 1 or 2...the next day he didn't even bother checking it out.???? Are these fish just picky? or is he stressed out? Please repy!!!!
