I have my tiger oscar with 6 silver dollars, frontosa, blue dolphin, severum, and an orange parrot. I know many people recommend not to mix continents, but my tanks-mates have been getting along well. Once in a while the parrot and oscar bump heads, but no big deal - it's short lived. I can say for sure that the severum and him been great from the start! They seem to almost want to mate.becikeja said:I currently have a 125G tank. Current inhabitants: 8" Chocolate cichlid, 4" BJ Jack Dempsey, 5 - 3" Silver dollars. I am thinking of adding an Oscar. Will the oscar be compatable?
