How should tank for a fish be displayed?

[Kal93]

I think if you have the right flow and the correct pumps and equipment....a fish would swim in your current if needed. Im not sayin its right to keep a 10" naso in a 4' 120g over a 6' 125g. Im just saying my point of view.

Agreed. I kept 3 resplendent anthias (2.5") in a 30G and they would swim against the current

I voted other. I like to know gallons but also the size.

I don’t quite see how you don‘t need both volume and dimensions to describe a tank?

A tank that is 20cm deep and 20cm wide (front to back) but is 200cm long is a “80 liter tank”... but requires a completely different consideration than a more “standard” dimensioned 80 liter tank.
