Hello everyone first post for me. Let me say awesome forum. I finally found out what my hitchhiker is called but not sure if it is safe to keep or get rid of. Can someone shine alittle light on this?
Thank you,

Nice mantis! Is it N. oerstedii?
Depends on what you want to keep with it. Crabs, hermits, snails and such are dinner for sure. Fish may be ok but it's always a risk. That puffer and the mantis likely won't end well one way or another.
