I just got 4 3/4 inch GBR's and 4 3/4 Gold Rams for my 75. Both sets where locally bred on tap PH so shouldn't be a problem with that and I keep my 75 at 82 so temp is no prob. Going to have to get some more plants as they grow and establish territories but that shouldn't be a problem. I Temporarily moved my Bolivian ram to a quarantine tank to ensure the rams settle in and grow a bit before they have to deal with the tank boss. When the tank settles down and I can get a few pics I'll be sure to snap some.
