Sorry to hear that David, most fish take a few goes to get it right, males mature after females so maybe he isn't fertile or doing the right thing yet..
Marklb put some pics up on an overseas apisto forum and the conclusion was macmasteri, true viejita are rather rare internationally so the odds of getting them come into NZ is quite low (of course it could still happen). Either way the 2 are very similar so no real biggie in how they look etc, I guess the 2 could cross breed if you did have a male/female of different types.
