Thanks! The RD is sharing a 125 with a few other cichlids about the same size (Oscars, Parrots, Texas) but with a divider of course. The larger one is in a 72 all by himself. I'm thinking about eventually splitting the 125 into 2 halves for the 2 FHs and then I'm going to transfer the O's to the 72. Then, hopefully in about a year or so I'll be in the market for a 8x4x2.
