Acro sweepers or pest?

[Enrique7]

Hello reefers! Trying to figure out if these are sweepers at the base of the base or some parasite. I think they are sweepers

Those are a little filter feeders. I wouldn’t say it’s a pest as I have not seen them reproduce. It’s usually just one here or there.

those are Coral boring spionid worms, and they do and can reproduce I've had one turn into two in a year on one coral but I've had a few on a montipora turn into over 50 in the same tank and I've had them in rock also I'd try to get it while it's only one or two. it's not easy but maybe you can dig it out when it's out of it's house.

I'd say it's a pest!

Agree, a difficult pest to remove. I had to resort to cutting my coral to get it out. They live deeper in the Acro base and those are just their feelers.

yeah I've cut the tube on an acro befor and missed the worm, it re appeared in a few weeks but the "frag" I cut didn't have it. I've also cut a branch and glued it to a frag plug and the worm is now on the frag plug. so it's hit or miss.

so when they are out go quick and deep. I've also not tried digging and superglue but I assume they will just move if you dont go deep enough, if the coral is healthy I just dig with a good tool and hope to kill them unfortunately I've let more go than I've gone after, this make me think about working on my issue now......

I wonder if injecting hydrogen peroxide (or Kalkwasser paste) into their tubes would be effective..

I have them as well, any other suggestions other than cutting them out?

Hello… I have been experimenting with different treatment options for Coral Boring Spionid Worms. I did not realize there was a worm that could tick me off more than Vermetid snails. When I finally kept the Vermetid’s out (100%), I’m so blessed to discover these little devils. Pic unknown...

Had one in my tank also
I dug out and glued the hole up
Thinking I had won the battle I monitored for a while and low and behold he popped up next to the dug glued hole

Very hard to get rid of
