Another question, it will probably be a stupid one, but do smashers dig burrows? My little guy looks like he kind of dug a tunnel under a piece of live rock but it's got two ends and he's never in it. Should I put more sand in the tank and add PVC tubing? Any general idea as to what my mantis is? His raptoral appendages are speckled as is his carapace, at least the part behind his head. I'll try and get a telson pic but he doesn't like to be out and about too awful much and I am afraid to stress him by catching him and putting him in a glass bowl again.
