+1 small mantis shrimp

3 of them came on some coraline frags. Should i be concerned?

Do you clicking sounds coming from the tank! Take a look at them online. Tend to eat crustaceans (clean up crew) and larger ones can be more aggressive with their feeding desires.

Hes tiny bout the size of my thumbnail. Havent heard any clicks yet.

Hopefully they're not the spearing type.

I imagine when the get bigger i can catch them or use a bottle trap to get them
