I've decided not to go for the sorority. I'm going to put Neon in the 10 gallon with 3 albino cories... and MAYBE 3 guppies.
He is a pretty laid back Betta so he should do okay in a community. Then, when I can, I'm buying a 20 gallon tank. Once Velvet heals I'll divide it into 3 parts... 2 small maybe 3 - 5 gallon parts on the opposite end of the tank and a big spot in the middle. In the middle will go 7 female Bettas! Velvet will go onto one side of the 20 gal and I'll get a beautiful rosetail, double tail, plakat, or halfmoon Betta.
So for now I'm not doing a sorority /= Just announcing it.
