And there I was buying a pair of macmasteri because I believed they liked the higher pHs! My tanks are at 7 (with 1 KH and lower GH). Is this way off? It may explain why they haven't spawned yet despite both being in high colour, high defensive mode, and the female disappearing into her flower pot for a few days every other week (this has happened about six times now). BTW, I've had successful spawns from caucatoides and bolivian rams in same tanks. A lone female checkerboard and a new pair of "green" rams are also prospering if not yet producing. Any hard info about macmasteri habits would be appreciated.
