The 20G is a tall tank. I am setting up another 10G in my little brothers room for his betta(it is with the shrimp right now). Btw, I will be selling most of the brichardis(babies and some adults). I am planning to keep only 1 male and 2 females after they first spawn in my tank. I think it is pretty cool that they all protect the young whether they are theirs or not, and that is why I am letting the whole group raise the first fry(I really want to see that behavior). I might even sell on this forum for like $0.50 per baby.
My main goal is to supply my LFS with them so I can get store credit to completely plant my 72G.
thanks
