I got lucky. I bought a 5-6" Trio from Dan of COA a couple of weeks ago. I threw them in with my Argentea and Silver dollars. Within a week, they paired up and got light. 60% water change, pot, saucer and subtract 2 fish...boom. Took me 6 months to spawn my Hartwegi. I wish they were all this easy. I need to enter this BAPs program. That's 4 spawns this year already.
