not quite sure its a Vulgaris, he has horns that come and go and is mostly out during the day. he eats readily from tongs and is very friendly, he has about a 1-1/4" mantle and about 6" legs, mostly a beige colour until spooked or when eating. VERY ACTIVE when light comes on for about 10 minutes then settles down, prefers to sleep in the bio material. and likes to mimic you, if you lean into the tank he leans into you if you back away he does the same, go figure, lol I have a few of these guys all the same at my facility this one i brought home to get ID'ed I will try and get better pics as well.
I am uploading a video tonight so i can post it here too.
