I have a M&F Rio Blanco growing out....hope I can get them to pair up........but the male is super agro. I will try the incomplete divider method, but the female is tiny.
This male was super aggressive and killed his female out at the farm. Introduced this female to him and the opposite happened. I had to divide them for his well being after the first spawn as she is much larger and more aggressive than females he's used to.
Thanks guys! Yeah the male is a very cool fish for sure.
These two don't tolerate any other tankmates regardless of size. They actually do better in a tank they can't see any other fish in neighboring tanks either.
Lotsa fry in the tank now. I'll update some pics when I get back in town.
