It's a Fluval View, 15 litre/~4 gallon. The filtration system is behind that central white panel. The shape of the tank is a flat oval. I initially had Fluffy in a one gallon cylinder but I didn't like that I couldn't see him very clearly because of the curved wall. He and I are both happier with the size and shape of this one (although I have had to finagle a way to baffle the filter strength).
Just got my fish! What name sounds best do you think?: Tango, Jude or moon?
his tank is a 2.5 gal from pet smart and he loves lying down on the rocks or in between the plans and the wall and barley ventures into his barrel/cave!!!
