Is a 125 gallon tank big enough for a midas cichlid, a jack dempsey, and a silver dollar?

Question

Reece the guy I would be buying from already has the silver dollar with the dempsey and they don't fight at all. I'm worried about my midas fighting with the others so I was thinking for the first few weeks I would put a divider in the middle of the tank.

Answer 1

YES, JUST KEEP UP WITH WATER CHANGES. THEY WILL HAVE ALOT OF ROOM TO CREATE WASTE

Answer 2

Yes, but I think that the cichlids might hurt your silver dollar.
