I know it does look like a earth worm but it definitely came from the detritus in my over flow box. I'm concerned because I have been loosing chalices and a few lps lately my sps are great. Could it be a peanut worm? Do they eat coral? Just lps coral? I started with dry rock and dip everything. But I can't figure out why some of my corals are dying. I have never lost a fish. Any idea's
Need to see this one in water. While not a eunicid worm, it could still be something dangerous. Or, just a typical detrivore. Your coral losses could be related to a pest. I would imagine the worm being hidden under it's main food source. So, this is most likely not the culprit killing your coral.
