Hiya,
I would think so. I've had mine for several months now and he's moulted at least once. Hasn't gotten any bigger then a quarter.
I've almost got mine trained to come out on command. When I drop pellets in the tank for the shrimp and crabs, he'll come out and fight for one. Really the only time I see him, but I've got a 39 gallon. He took on an emerald more then twice his size for one! Must have stung the Emerald with his anemomies since it jumped back. You'll probably see him more in a 5 gallon.
