Hello fellow fish forum friends! So I have this old 2.5 gal "tank" that I used back during my uneducated fish keeping days...I have a filter and heater for it...is there anything I can keep in a tank that small without being cruel? I'm not going to force anything to live in there if it's not a good idea (hence why I'm asking) but wanted to ask the experts!
Thanks all!
Thanks all!
