Will an urchin kill peppermint shrimp?

The reason I ask is because I have never had a problem keeping these shrimp and they have always helped keep my tank clear of aiptasia. Over the past 3 months I have added like 8 pepp shrimp and they keep disappearing. Well I noticed that my urchin was all up on one that was in the corner alive. I keep knocking the urchin down and it keeps going to the same place. Actually touching the shrimp.

Thoughts?

When we had urchins they never seemed to pay any attention to the peppermint shrimp

No, they are algae eaters

Didn't think they could move fast enough to even be a threat to a shrimp

It's really weird. The shrimp won't run. Maybe he's not threatened.

 

[that novice guy]

well do you have any other fish in that tank that would love to make a meal of a peppermint?

I am now thinking that maybe an anthias I have might have been killing them. The shrimp now I believe was trying to stay close to the urchin. Urchin moved and the shrimp went an was clinging on for life on the teeth pf the overflow. I saw the anthias darting up at him. Grrrrrrr!!
