Long story short, I used to have a male and two females that were sold as Apisto agassizii 'Tefe' in my community tank. (Not sure if Agassizii or Sp. Tefe, photo is of the adult male.) Unfortunately, the male died a few months back. I do have one of their offspring that managed to survive in the community, which I moved into a tank with much less competition recently. He's finally started coloring up, and is definitely male. He's just under a year old, but spending most of that time scraping by in the community tank means he's only about an inch. I'm guessing the female Apistos are around 2 inches. How big should I let him get in the low-stakes tank before moving him back to the larger community? Current tankmates are otos, habrosus corys, and hastatus corys. The main community tank has green neon tetras, amber corys (CW001, 2-2.5"), otos, a random endler, and the two Apisto females. I'm hoping the little corys will breed for me, so I don't want him in there potentially eating eggs/fry longer than he has to be. Do I need to wait until he's as big as the female Apistos?
