Where did my blue devil go

Where did my blue devil go?

I've had him for a year in perfect health.

2.5 gallon tank
5 lbs live rock
7 green Zoas
peppermint shrimp
tiny hermit crab
red grape algae
no overflow (internal sponge filter)
glass canopy

I recently added a clump of Chaetomorpha filled with copepods. One jumped out and was somewhat large, about 1/4"-- could he be the culprit?

Blue devil.....damsel?! :scratch:

I don't think a 1/4" copepod could devour a blue devil damsel. The blue devil may have jumped out of the tank if you can't find it inside.
