Yellow goby

Think I got it.

 

Hermits are as big as a five cent

 

Well is does look like an injury. My clown and my YWG have gone at it and locked jaws, injuries never occurred though. I wonder if you have a crab in the rock work that went after the fish. Not much you can do at this point but wait and see. If you have a breeder box and you get the chance to remove the fish I would put it in a breeder box for closer examination.

 

An emerald crab? There should be one in there but I don't think it is since I'm getting bubbles algae again.

 

Coralline, my YWG is doing good. The jaw appears to be healing and is eating. I've seen it swimming about 3-4 in from sand in the middle of the tank. I introduced a red with blue legs pistol shrimp on the tank this past Saturday and I'm just waiting for them to find each other. Geez, the only way I know pistol is there is because the sound of it's claw. Thank you!
