piranhas not eating?
weird situation
mabey its because u have wayy to many in that small of a tank
and they are probobly stressed
i found they are more aggresive when they are in smaller schools
atleast mine are
ive had 13 before and they were always skitish
but when i sold em and kept 4 they were very aggresive

when i had a big school 24 red bellies and terns. they were kind of skittish, once i trimmed down to 4. they are insanely aggresive. the fish would charge to the front of the tank when i walk up to it. where as before they would try to hide behind one another..

if your fish is not eating then your water is MESSED UP!.. bring a sample to the LFS to test it before its too late..
