Unidentified pest after Zoa dip

[gingeramoeba]

A couple of these bugs came off my zoas after dipping. They are very small, 2-3mm. Mostly translucent. They have 2 thin long antennas on their head. I looked at photos of Zoanthid-eating nudibranchs and those are much thicker than what I found. Are these just amphipods? I do have amphipods in my tank. Trying to figure out what is irritating my zoas and palys.

That’s what i was guessing. However, they may be good for some things but, they walk all over my zoas and irritate them so I moved them up to an isolated area and they seem to be doing better. Thanks!
