just got mine about a week ago hes been hiding in a little cave comes out now and then. he is gettin alittle braver but still goes into hiding once you get about 3 ft from tank
I also got one recently. He constanly picks the rocks and the back of the tank. Likes to perch on the heater and power head. He hates hermits and if any crawl near his hole, he bunts them off . A very good addition to a tank I think.
