Hi all.
I recently purchased several coral frags from an online vendor. Some are thriving, but a few are retracting/dying. My tank is about a year old, started with live rock. I have other coral previously purchased doing well also. Tank parameters seem in line.

I'm not sure if the frags are just dying from the shipping stress or flow/lighting issues. But tonight I checked on them after lights out and noticed quite a few worms all over the issue corals. Any thoughts on an ID for these worms? Could they be my issue? I've attached a video of an example.

Thanks in advance!

Can't see video, you need to upload it as a .mp4 or as a youtube video. To convert your current .mov video go to any file convert website like free convert. Then download the converted file and upload here, sounds complicated but takes maybe 40 seconds. Or make a youtube creater account and just upload the video and post the link here.
Tech support soapbox over. Good luck :)

Sorry try this:


Almost seems like some type of copepod?

Not worms - these are either an amphipod or isopod. I would guess amphipods, but I can't see the critters well enough to say for sure; there are reports of amphipods occasionally eating corals in our tanks, though, so that would seem to support that idea.
