Sold as a twenty long anyway, the actual internal volume can vary a bit depending on the thickness of the glass and the shape and size of the plastic frame- most of them have a capacity somewhere around eighteen and a half-nineteen gallons.

I only mention it in case there was some reason why it might matter.
