What in the? Missing fish and fin!

So today I’m checking out my 1 year old innovative marine tank and I notice I’m missing a blue chromis and my other chromis is missing a tail! What the heck happened? I have no power heads in the tank. I have 2 clowns, a mandarin, a crab, and 3 snails... any ideas?!

They were fighting and one may have died. Chromis tend to do that

Well I found one chromis.... it’s with the crab lol

Glad you found it but agree also with other response. They do kill each other.

This is purely aggression and not surprising. Same applies to damsels.
