Is this an amphipod?

[brrdawg]

Seen bunches of amphipod like creatures crawling all over my rock. Is that what this is? Is it a problem? This Zoa just doesn’t seem super happy. Params are in line and all my other zoas are doing well.

Are you referring to the ovular dark spot on the bottom area or the circular spot to the left of the zoa? Maybe try and circle it? I can't really tell from the pictures, personally

Here is another one. Under a little different lighting.

Can't say I'm 100% sure from the pics but I'd be pretty confident it is. Do they look like this?

Someone I'm sure will correct me if I'm wrong but I highly doubt they are the reason your zoas might seem bothered- bar them just touching them as they run along, they detrivores and IME don't have any negative effects on coral

I can’t really tell looking either. They are super small but do have two tentacles. They seem to just climb around on the rock. Thank you for replying. New to the hobby and loving it so far. Just stress over corals…haha

I'm almost positive despite not being able to see that they are amphipods. If you really want you could try a video but it's probably fine. Believe me, I'm a fellow anxious reefer myself haha, it happens. What's wrong with your zoas? They seem fine in the pic

I think it is ok just seems like it is doing an umbrella from maybe too much light? I really appreciate your help. It is so much fun doing this hobby but can really stress me out as I want to have success.

My guess would be a Munnid isopod, which have flattened backs (Amphipods have curved backs) and are beneficial grazers. I cannot say for sure though, since the pictures are quite blurry (as @cdw79 mention above, a video would help with identification).

Thanks so much! I think you are dead on that it is a Munnid. Never heard of them before but hope they are fine. Mine move just like the video you provided. I really appreciate your help.
