How many crabs in a 20 gallon tank?

[RayLovesHermits]

All would be PP's and Micro/Small size how many could live in there comfortably?

I would only put 3 and maybe 4 if you really want to but you would have to upgrade when they start going on to medium. I only have two in a 20 gallon long and would last a lot longer then having more.

I agree. 3-4, but they will grow over time and you'd need to upgrade to a larger tank.

Okay! So when they upgrade about 3-4 in 40 gallon?

It can get really tricky with actual numbers. If you have a bunch of marble size crabs you could fit more. If they are the size of a tennis ball it would be less. Eventually they will all grow and you will need to upgrade to a larger tank.

This should help explain it a little more.
