The one in your hand is a brittle star and that is about as big as it will get...the type you have are tucked away in holes and cracks of live rock and is a good part of CUC. Normally you won't see but a leg or 2 sticking out of rock during daylight but look in tank after lights out and you'll see a lot more.
They do get big though.
