All depends on the temperament of the Jag and size of it's home, mine's in with all sorts, Pacu, RD, GT, Dovii, Barbs, Clarius Cats, TSN, Perruno, etc and it get's on fine with all of them.
It's a 6x2x2.Sab_Fan;3362905; said:helps to know how big the tank is . . . assuming a very large tank - - say 6x2x2 - - I would feel safe in trying Texas, Oscar, Salvini, Festae, Midas . . .
could also try several Convicts, Rainbows or other tough smaller cichlids
I have had larger convicts in there, but they spend a lot of time hiding. I have two in a 100 gallon tank, and finally found a female that the male dosn't try to kill. When I introduced her in the tank, they were digging a nest within 20 minutes. Now I have eggs. Some have turned white? Hmmm. But usually my large male (like most jags) sees other fish in two ways. If it fits in his mouth, it's food. If it dosn't, it's a fight.im guessing other sa/ca cichlids in a rather large tank
