I have a firemout cichlid and he makes me very angry. So many on the internet say that they are a rather peaceful cichlid so i decide to get two. One killed the other when they were still little babies maybe an inch long. Still about the same size i have this firemouth in a 46 gallon bowfront. Also in this tank are a small green severum maybe a little bigger and certainly taller and a small pacu. Don't ask about the pacu I am houseing him for a little while hes the largest at about two inches. The pacu gets destroyed by my firemouth and the green severum is not so bothered but what should i do with this firemouth am i going to have to keep him alone 46 gallons all to himself??????!!!!!!! I see people on youtube with very successful tanks around my size or 55 gallons with quite a few cichlids and nobody hurts eachother are they just lucky as anything or doing something different?
