I have a bully tetra! I have 2 males and 1 female (believe since it's hard to tell on red eyes!) One male is larger and harasses the female and male; he also goes after my phantom tetras. During feeding I have to really spread the food out or he will guard it from the other fish. I only have a 10 gallon tank right now so I don't know if I could really increase the school size at the moment. I have a Betta and a Rhino Pleco in the tank also. Any sugestions on how to calm him down for the moment?
