Mantis?

[tmbar19]

We bought a complete 90 gal. set up a week ago. When draining the last of the water, there was this little 1/2" pale blue shrimp-looking thing. We thought he'd be "food" for the fish, but didn't have anywhere else to put him. Unfortunately we didn't know any better, and slipped him in the tank. Mistake! Now we are trying to trap him out. We hear him "snapping" occasionally and he's smashed up one of my little hermits. I was told not to destroy him, as many people like to keep them as pets. They are supposed to be very intelligent. Hope he's dumb enough to get caught! Marianne
