Ok, I got quite the surprise tonight. This guy came out of wherever he was hiding. He’s probably twice the size of an emerald crab I’d say. And I didn’t add him. Haven’t tried to ID him yet. He’s quite a bubbly shape crab of some variety. I haven’t added that large of a rock that he could have hidden in I don’t think. My rock all went through an acid bath before curing it. Could he have grow this large in just under a year? I’ve seen some really small dead ones kind of like this while vacuuming my sand. But if he came with my live sand, could he really have grown this size?
