can you put a photo?

Hmmm thought I did! Let me try again. If it still doesn't work, I'll post when I get home. Don't have the best service at the moment!

You would need to see the meral spot to fully id the species, its on the inside of the "forearms"

OK, well if I get a decent Pic I'll post it! I'm not hopeful though 😂

Not easy 😣, there is a lot of mantis with white meral spot.

Maybe Gonodactylellus espinosus??

Or Neogonodactylus curacaoensis??

This one is found in Caribbean, Florida to Panama and Curacao.(in contrary to Espinosus which is only found in center pacific)

I would guess at N. Wennerae or N. Bredini. It might take a few moults to truely id as they do colour change depending on collection area and depth as well as aquarium lighting playing a part

@Ratvan@Ratva soooo the question is, can I leave him be?? I know once I move my CUC over, they will be in danger, but I'm not attached to them.

How big is the Mantis? I still seem to have all of my snails but I do purposely feed mine live feeder shrimp

Your shrimp and snail will be in danger. Your fish less, but it could still happen. 

Mine didn't kill any of my snails but it is still a young one. However my 30€ pistol shrimp disappear and the only possible culprits at the time where my two hitchhikers: the mantis and a small gorilla crab.

Maybe an inch and a half?! I hate to have to kill him. The gorilla crabs on the other hand😒 it's unnerving knowing I was stacking and rearranging this rock with all of those in there. (I saw 4 👀

Nice find! They're such a cool animal.

 

Don't kill him. You can probably find him a home, they're in demand. You could put him in one of those breeder box things for a little while, as a temporary enclosure to find him a home. 

 

For the gorilla crabs, make sure to kill them humanely. There's evidence crustaceans feel pain. Either crush the whole body in one go so the brain is destroyed before they feel anything, or humanely euthanize with clove oil. You should have clove oil on hand anyway, in case a fish is sick or injured enough that it needs to be euthanized, but clove oil is best to humanely kill pests.

That’s an excellent score! If you don’t want him, I’m sure someone in your area would take him. If you can get some better pictures, I may even be able to help identify him. 
 

Given enough time, he will kill your gorilla crabs. When we got ocean rock with gorilla crabs, we put one in with our G Ternatensis, and she killed/ate him.

Leave him... he will eat those crabs. CUC is easy to replace. Quick moving fish will likely be fine with such a small mantis as long as he has something to hunt or if you feed him.

 

This is one I been following on Humblefish forums. They are a hoot and the fish always looking for handouts from the shrimp too lol

Aw, look at the little fella go! They're such a strange group of animals, stomatopods. Almost remind me of centipedes. I should really get a mantis one of these days, maybe in a 'fuge.

Wow! I was thinking the same thing. Just replace the CUC as needed and keep him. I would guess a Yellow Watchman Goby would be out of the question though since they hang out down low, huh?

Definitely don't put a shrimpgoby with a mantis. The mantis might or might not try to eat it, but would almost definitely get territorial.
