Mantis shrimp identification. He’s killing everything

[IKD]

Did you buy it in water as well?

I did not actually, but I live near Orlando so it wasn’t a long trip. Bought it last October and also had a couple bobbit worms that came along for the ride.

Definitely not a peacock... any size peacock will look exactly like an adult!
Look at some of these to determine it: https://ucmp.berkeley.edu/arthropoda/crustacea/malacostraca/eumalacostraca/royslist/index.html

If you don’t want him, will gladly take him if you’re willing to ship!

this seems to be the best match: https://ucmp.berkeley.edu/arthropod...raca/royslist/species.php?name=n_curacaoensis

Also all the popping sounds might be pistol shrimp

Something else to consider is a protein skimmer. I thought I had a mantis and it turned out to be my ib tank skimmer filling up and ejecting the lid against the hood of my tank making a popping noise lol. I felt like an idiot
