Question in dmail from a random user:
If you fill it with water how many fish can live in the server-rack that e6 is hosted on?

Answer (mostly from bitWolfy):
It depends on the fish; the rule of thumb is 1 inch of fish per gallon.
A 42U 19-inch server rack can fit about 263 gallons of water.
So, you can house 8-9 fully grown salmon in it. Or 121 betta fish.
