I'd say a minimum of three so they can have some company. I've had groups of three in a couple smaller tanks for a long time and they seem to be doing all right. I've also had lone survivors from larger groups do fine for long stretches. However, when I can keep a larger group (6+) they do seem to be out and about more. In both large and small groups they seem to like to be near each other a good bit of the time so I try to make sure they have a couple pals in the tank.
