How many tetras?

[Gish]

Don't know if they will either. maybe with enough caves/rocks/territory they might.

Just what I've read. I've never tried Fish breeding with any species

Got 2 apistogramma viejita from my LFS. They were all juveniles and I think I got a male and a female. Are they to small to sex? The larger one chases around the smaller one and then flicks his tail at the smaller one. The small one is barely 1 inch and the other one is almost 1 and a half.
