Hello,
I am looking into wanting a used small tank. 2 gallon tank at the most,No extras needed, just the tank, to be able to keep my Betta in for the days that I have to clean out his main tank.
I just have a fish bowl, for now to keep him in during the cleanning process of his tank.
Any help would be greatly appreciated as I can not affored to buy another tank new .If you can help me out please let me know. Serious sellers only.
Thanks
