ok first the tanks I have, I have a 180 with a male 8 inch red terror and nothing else but a silver dollar and a tinfoil barb. I also have two 40 gal breeder one with a 6 inch hemichromis fasciatus and the other with 6 juvenile 3 inch festae growing out. I am about to get 4 juvenile hemchromis elongatus but not sure what tank to put them in. If i took the male red terror out could i put the juvenile festae and elongatus together in the 180 or could i put the male hemichromis fasciatus and the male red terror together in the 180 and give the hemichromis elongtus juveniles their own 40 breeder what do u guys think?
