Could just be a coincedence, but now I'm wondering ...
I didn't find anything on the web about urchins eating acans
Yesterday, this particular colony was fine, now it's missing more heads
The rest of the receding acans are unchanged

Mike, I've cut my lighting way back, so I'm hoping to see a difference

Shelley, I read about someone losing acans and finding a kind of bristleworm in the skeleton. Kinda like being eaten from the inside out maybe ...

Seriak, it seems that none of us can keep all the kinds of corals we want to. Some of us lose 'this one', and some 'another'
I'm just happy to not have lost most of ours

I just pulled out the acan that is currently suffering the most as I found it in the clutches of the urchin last night and was preparing to re-glue it

I decided to remove all the old glue first and wouldn't you know it, there are worms inside the underside of the skeleton
It's currently in a dip and I'll post pics once I'm done

Hopefully this is the cause and the recession will end

There were 3 worms in the skeleton. Looks like fireworms maybe ?
This is the largest of them - about 1/2" long

wow I better make sure I dip everything before I put it into my tank now, Scary after seeing what happened and what pest may tag along.

The worms I've found before are red and more thread like.. No bristles. They live in tiny holes burrowed into the skeleton. Soak in water with a bit of Hydrogen peroxide seems to get em out!
