Who ate my shrimp???

By carcasses, you mean that you saw dead pink bodies on the gravel, right? If you saw what looked like clear empty shrimp ripped in half then you're probably seeing the exoskeletons that they leave behind after molting.

However, I wouldn't put it past discus or rams (if the shrimp are small enough) to eat your shrimp. Even if the shrimp aren't small enough to be swallowed whole, they may be picked on to the point where they die.

honestly, it couldve been any of your fish, with the bottom feeders being most likely.

Nah, hillstream loaches won't bother. Neither will ottos, corries or SAE's. I have the last 3 in my tank and they don't pay attention to my ghosts at all. The ghosts have been in with the cories for so long now (over a year now) that they're not even affraid of them. They'll even try to shoo them away when a cory has a piece of food that they want.

The pleco, though, might be another story. Although, if a pleco were to eat a ghost shrimp, I doubt there'd be any remains to be found.

One thing that I did forget about is the vulnerability of newly molted shrimp. Unless they have a place to hide and harden up, they could become snacks. But, still, I would focus on the 2 species that I mentioned before. Tetras probably aren't too inclined to poke around the bottom and all of your bottom feeders, with possibly the exception of the pleco, won't even notice your shrimp.

Discus and Rams will devour the shrimp. I have had rummynose tetras poke at my cherries too.

Serpae's might too, if they could find one after a molt.

I have the same problem. I think all of my now deceased killies were the culprits. I saw bright pink headless shrimp bodies, and now I only see about 2 ghost shrimp left.

The ghost shrimps turn pink when they are dead. When there's just an exoskeleton, that means that they are molting, and therefore, are growing a new, larger exoskeleton to suite their growing bodies.
