Glad your tank has come along so nicely! That engineer is cool looking btw, he's huge! LOL Mine was about 1 inch when I got him and now he's like over 8 inches long, give or take and inch or two. lol Mine however does go from rock section to rock section and makes burrows. He has about 6 rocks involved now in his HUGE mansion, he can pop his head out from at least a dozen spots to check me out or to grab some food. lol thats the only time he comes out all the way, is to grab some food. It's really cool how he shimmers when he juts out though, I love watching him. i also named mine, he is "teddy bear" cause he has the cutest little teddy bear face. lol
yep, I am weird. I know it but I love it.
Good luck guys!
