    The old rule of thumb was 4 gallons per inch, but that has been holed a bit by the fact that 4 chromis will not produce anywhere near the waste of a 4 inch tang, so not a bad rule of thumb to work with, but remember the potential girth and depth of some fish compared to others.
    Also bear in mind you should use the full expected adult size, but don't assume that the fish might not reach that size in an aquarium.

    Allot of factors need to be taken into account, such as what fish, what inverts, what skimmer, what type of maintenance, etc. Many people also say a more important rule is inches of fish per surface area.
