Can't pm you back, you box is full. Mine is a G. Smithi. From what I understand he may get to be 6" when full grown. Mine hits anything that goes into the tank, he's aggressive. Will hit the feeding stick, cleaning tongs, syphon for water changes, and the cleaning magnets. I DO NOT put my hand in the tank unless it is absolutely necessary and then I cover the entrance of his cave with a net to give me a shot of getting my hand out of there. My camera has been in the shop and just got it back, when he is out and about I will snap a few more pics for you.
