Thank you for the replies all....
Timbo, I think I got all the mantis out hopefully (1) before putting in tank. He's in a bucket right now with SW
and I am making plans for my refugium so maybe I can keep him around in the fuge and feed him shrimp or something.
No taps heard in the tank yet either.. the rock was shipped with moist paper and just a little water at the bottom so I am thinking/hoping that the only mantis there was, jumped out into the pool of water in the bottom of the box where I found him.
I had looked at many pics prior to seeing one for real today, and he was a dead ringer, so into a bucket he went. He occasionally taps in the bucket.
I didn't do a FW
dip because I was wanting to not hurt any fragile life forms, and I thought I would just take a gamble in hopes that there were no more mantis. I didnt know which decision was better or worse to do.
I guess I will find out eventually......
