fish gone

i have an emrald crab a sally light foot and a skunck cleaner shrimp and a white tail pygmy angel will any of thjem eat fish or coral

 

1,How big is you sally light foot ?
2, how big is the fish that disapeard ?

Ive seen sally's have no problem's going after damsels/even small tangs.
and the like.

 

sally light foot is about a little bigger then a half dollar and the fish was about 3 inchs long the sally light foot was eatin it when i found the fish

 

well it's possible the fish could have fallen ill and laid down some where'
ya just never know.. but sally's can take a seemingly healthty fish.

 

I doub't the sally killed the fish but crabs are opportunistic feeders so if the fish was not healthy or it did lay down for some reason you never know and once it was dead all of the inverts you mentioned would have definitely gotten in on the feeding on the dead fish.
