There are just so many bettas I want at LFS, and they are in such sorry shape, so I'm reaaaallllly wanting to get this done. I have room for the 6.5 gallon bookshelf tank from Petco, and I have some extra filters and substrate. I'd need some plants (buying some more for my 20G anyway, I could break them up). My question is how to I divide it? Would it be a bad idea? I'd use the plants to block line of sight as much as possible, and also would get a heater.
Also, I'd QT them and heal them up before adding them all.
