I keep looking at my tank and it still seems empty. Lol. I've been doing better so i can up my water changes to a fuller tank. I hope. So how many more bettas does everybody think i can add. 75 gallon 2 male betta 13 female betta 12 glowlight tetras 9 emerald cories 1 pleco. He may end up with the tank to himself if he ever decides to start growing.
