Help! Dissapearing fish

[Roblox84]

I've had 3 green chromis get eaten over the last year and I was wondering which of these do you think was most likely to eat them? A tiger stripe serpent starfish, a brown serpent, a coral banded shrimp, or an emerald crab? None of these get fed so they are probably hungry most of the time. These animals are also fairly large since they have been in my tank for two years. Any suggestions as to who's eating the chromis and who will be the lucky one to get pulled out of the tank?

How do you know they're getting eaten and not just dying and then getting cleaned up by what you've added as a cleanup crew?

I would not rule out Chromis aggression within the group. Many start with groups of chromis and they slowly pick off the weakest of the group 1 by 1.

That was my thought, one killing the rest & the clean up crew doing their job...

Well my fish aren't really aggressive to each other. I have a yellow tang, blue tang, goby and clown. The chromis been in there for a year so I figured if a fish killed it then the chromi would be floating at the surface or eventually skimmed by the hob overflow.
