Shrimp going missing

[forestwalker101]

So my dad has a 98 gal corner reef tank and we had two cleaner shrimp and a coral banded shrimp that went MIA at different times. Any Ideas what/who the culprit might be? We never noticed anyone picking on them and havent seen any remains. They had been in the tank for a while so i dont believe it was a acclimationacclimation issue. Ph 8.0 ammonia, nitrite,nitrate all zero. Temp 80.2 salinity 1.0215.

Same thing happened to me…found out that my anemone eat them

I have a 6 line wrasse that is a serial murderer of shrimp and snails

And green brittle stars can catch & east sleeping fishes so maybe they one should be in the suspect list too?

Do you guys happen to know if a 6 line wrasse would eat peppermint shrimp? I had some go missing a while back and I figured they just died. But... if the fish ate them, that makes sense. I always figured their mouth wasn't big enough.

 

[ColoReefer970]

Mine would...he doesn't need a big mouth to kill things, he just batters it until it stops moving, then picks off little pieces over time

[He's well fed too...just a psycho I guess]

Crap. I've read that fish don't normally bother cleaner shrimp because of the "premium cleaning" they get. I suppose I'll just have to settle for a cleaner wrasse in the future.

I'd steer clear of Cleaner Wrasses. Most of them seem to die relatively quickly in aquariums, and Coral Reefs experience nasty side effects when they're removed. I'd just get a Cleaner Goby if I were you.

Ahh yes, I've read about those. Thanks for the input

The royal dotty and 6 line are pretty small still. I haven't seen any evidence of them harassing any of my inverts. My guess is the brittle star. There were no carcasses left at all. If fish tore them apart I would figure there would be some sort of crime scene. The star would just swollow it whole. My keyhole angle is in the top right for some perspective on how big the star is.

I've seen bristle worms and hermit crabs clean up a carcass pretty quickly. If you had a shrimp die before you went to bed I wouldn't be surprised if it wasn't missing by the morning - especially if it was drug beneath the substrate (i've seen that happen to molts).
