I saw petsmart selling this crab, I was wanting to know if they got bigger, or will they remain mini?
it gets bigger, then you eat it.
If you have fish that live on the ground, forget crabs.They'll only unrest them or eat them even.
Looks like Uca pugnax. There's so cute! ^.^It's a fiddler crab. The one shown is a female. The mles get the one enormous claw. They don't get much bigger. The largest I've seen is about the size of a ping-pong ball.
