I think he has a female dovii and some sort of pike in a 75, that won't work. He has a butti in a 55 or a 40, which is too small for the fish. He has another rd in a 40 or a 55, unless its a female it won't work. And he has another rd in a 30 something gallon. I think it's important to know if he has that pond since he claims he will move his other fish to it since they will outgrow their current tanks.
