(Admin sorry for opening a new thread I forgot a name of my old one)
So, this is my 13G dark water Amazona tank with neon tetras and male PK betta as base fish, and supporting role are corydoras, otocinculus, nerita and helena snails. As the name applies a tank is in my office

. I've choose this betta because of it's similar color with neon tetras. Here are some pics of tank and fishes. Enjoy.
