    As a guide to stocking levels in a reef system, allow 2.5cm of fish per 23L of water. In a fish only system allow 2.5cm of fish per 11.5 liters. Stick to these levels for the first year of a tank's life.

    There can be no hard and fast rules as no two aquariums are ever identical, but, by being conservative during the first year chances of success are greatly enhanced.

    i dont agree with this metric at all...

    there is more to stocking levels than literage, species of fish, territory behavior, filtration you have etc.

    You also have to make sure that if you're using a calculation like this, you work on the mature size of the fish, not the current size!
