I kept one in Sacramento tap water (pH 7.6, med hard, low alkalinity) for a couple of years. It grew to about 10" on pellets, flake, etc. Never bred them, though.
I'm in a similar boat with a pair of haitiensis. It's definitely a male and female. They're big fish. Lots of tubes and mouthfighting...but no spawn to date. My male is a couple of inches smaller than the female, which might be the issue.
Anyway, I'd figure out wehat foods they really like...feed them a bunch of that for a couple of weeks... and then do a 90% water change.
Good luck,
Matt
