people keep saying firemouths are semi aggressive or peaceful while all of them are aggressive my friend has a firemouth too hes a mean guy just like mine, will flare to other fishes if it cant bite them push other fish around, and even fight. i also saw firemouths at the store they all are active and nippy so i think people should change their profiles, they CAN NOT go with community fish, my question is will my mean 3" firemouth get along with 5-6 tiger barbs in a 20 gallon tank? also where can u buy cheap tiger barbs? the small ones are 3$ each at my petsmart i could save some from walmart quarintine them and stuff but i heard they could cost the same price at walmart as people think tiger barbs are not schooling fish WRONG theyll kill each other in a group of 3 or 4, i dont want to spend more than 20$ on tiger barbs
