aimara can be keept in a 60 gal tank(till 30 inches) , it doesn't need space just good aeration and filtration
YOUR Aimara might be kept that way.......
Most people keeping them have bigger sumps then that
, AND put much more value on giving it a proper home. I do see the silver lining though, when it dies you could just bury the entire tank instead of having to extract it....... I wouldn't cram a common wolf in a 60, let alone a wolf that actually swims.......
