A. baenschi is my favorite Apistogramma thus far (I have kept 8 species to date). I have two pairs currently, each in a ten gallon tank loaded with plants and leaves. I was not planning on keeping them long term in the 10s, but they are doing so well that I am going to hold onto them until I can furnish larger tanks. The two pairs are spawning regularly.
I think they are a perfect species to start with. You will want to start with more than a pair ideally, as they can be picky about choosing mates. From what I can tell, they are not as picky as A. panduro.
The males are beautiful and I have not had issues with them beating up the females. The females are on the higher end of the aggression scale when guarding fry. Considering the amount of success that hobbyist have had with this species, I would not consider them difficult. The females are fantastic mothers.
If you are near SC, shoot me a PM. I can pull some fry for you.
