Yes i need a dwarf. I already have the Bolivian Rams, And there is no reason not to have them is there? And no particular biotype right now, But the water will have tannins in it from Wood and leaf litter and the plants will be Stargrass,Bacopa, Hairgrass, Braz Micro Swrd, Dwarf Sag And other various Sword Plants. Oh and some sort of red plant.
