Hello all! Currently setting up a ten gallon blackwater tank that, when complete, will have a PH in the 4's and TDS in the 20's or lower. I've been considering keeping a pair of dwarf cichlids in it, but seeing how this is only a standard 10 gallon I was not sure any would be truly happy in it. Any apistos (or other blackwater dwarfs, for that matter) that would work? Thankx!
