Cleaner shrimp dissapearing

[Michael Adam]

Has anyone had the following fish take out cleaner shrimp? This is a recent thing. I've had cleaner shrimp up until a few months ago. 3 have gone missing hours after putting them in. Sat and watched for an hour or so and don't see anyone picking on them. Come back and they are gone. Thanks for any help.

Either they were eaten or there is a space wormhole opening up that they are slipping into? I have a fish that decided to go into every overflow option it could find, so maybe they slipped away into an overflow? I caught my fish in a sump after he jumped into the overflow that went into another tank and from there he went into the next portal and found his way into the sump.

Looked everywhere. They are gone.

They are fragile, may have died for who knows what reason and then your CUC did its job.

CUC will be on a dead shrimp like white on rice on a paper plate in a snow storm.

i saw my gramma attack a newly introduced fire shrimp when it tried to hide in the same spot that the gramma had declared as its territory
