Crayfish?

I believe they need 20 gal. each. Some only get up to 6 in., but some get up to 12. It depends on what kind you get. They are very territorial, so if you get more than way make sure it's a big tank. Otherwise they'll attack each other. Also, you want lots of "caves" or hiding places where they can go to claim their own space.
Brinny,
It really depends on the type of cray.
What species did you have in mind?
The most common N. American varieties of crays that you would find in fish stores get to be about 7 inches in length.
Many fish stores that sell crays also have Redclaws (species name Cherax quadricarinatus sp?)---which are native to Australia and can get to be about 12 inches in length.
At the same time, there are some dwarf species of crayfish that remain quite small.
My experience is with N. American crays that stay within about the 6-8 inch range (although none of mine have grown that large yet), and they all do fine in smaller tanks.
Let us know what type of cray you're after, and we can tailor our advice accordingly.
