Is my maroon clown paired

what do you mean by "were/was in half"? They were physicaly split, as in killed? If thats the case..I would leant more to you having a mantis shrimp hiding somewhere.

Do you ever hear any clicking sound in your tank?
What are your water parameters?

is a mantis shrimp visible cause i dont have any other shrimp in there and all my water parameter are in great condition i test them weekly. all that i have left in the tank are all my corals 1 turbo snail, 1 hermit crab im thinking its my female maroon cause it very aggressive towards everything the comes near they're anemone because it is a small tank. i think they're gonna breed because they are cleaning a spot on a flat rock.

What size tank?
A mantis can hitch hike and be small enough that it can hide, so you might not see it.
I doubt a maroon will split you critters in half.
What worries me is the fact that so many were killed.
Can you post your water parameters? "great condition" can mean many different things to different people.
