This Ancylomenes is common at Kwajalein and associates with a number of sea anemones, including Cryptodendrum adhaesivum, Heteractis aurora, H. magnifica, Macrodactyla doreensis, Actinodendron arboreum, A. plumosum, Heterodactyla hemprichii and Stichodactyla haddoni. A particular anemone may host numerous specimens of the shrimp, which may rest on the anemone's tentacles or hover above it. We have seen this figured as Ancylomenes tosaensis but the ID needs confirmation.
This one is on Macrodactyla doreensis, the corkscrew anemone.
On Stichodactyla haddoni.
On Actinodendron plumosum.
This one appears to be on Heteractis magnifica.
The one below was on a colony of Goniopora coral.
