I'm probably just being the worried mom but my mantis has not shown himself since i put him in the tank(5 gallon nano) a week ago nor has he eaten anything(as far as i know). There's a snail and hermit crab roaming about but he hasn't caught them yet and i've offered planlton and krill without any sucsess. Any suggestions? I read the other day that waving food in front of the entrance of the lair might encourage the mantis to come out.Problem is i'm not entirely sure where he's hanging out. Any suggestions would be appreciated...thanx.
