OK, so here is the plan for my sorority tank. :)
Heavily planted, already has lots of hiding spots! BTW, they will be LIVE plants. 20g filter. 4-5 betta girls, ghost shrimp, and possibly two Otos...I just don't know if that is too much!! It will have live plants, so that should help with the bio load, and a filter that is very powerful... I just don't know
... Any thoughts?
