Bristleworms?

 

[Joker79]

I do have bristle worms. Would they do this??? Eeeeek

 

[Browncoat]

Bristleworms won't do this

 

[vic67]

I would dip what's left of them and keep them in shade and low flow; away from everything else. I can't tell you what caused it but I don't think it was bristleworms either.

 

[Joker79]

I did dip them in coral rx for the first colony and revive for the 2nd. :-(

That is strange. Did you move them to a spot that had too much flow? Well anyways how long have you had them in the location? What kind of light and flow are they getting? I'd say 1.025 is more idea and 7.7 needs to come up to 8.2

 

[jordan banks]

Also soft corals can do this by chemical warfare.

Make sure that you do not throw out the skeletons... I have been able to recover acans that had no visible tissue on the skeleton. They can come back from what would seem like nothing.

 

[jordan banks]

That's interesting I'm wondering if that is something they do periodically. I've had two small colonies do that as well and they are making a slow comeback.

I have an acan doing this right now and I would love to know why

 

[jordan banks]

I think it's caused by too much flow.

 

[Joker79]

I have noticed a couple "unknown" tentacles from behind the rocks that I don't know what they are. I'm going to do some flashlight searches here in a couple minutes.

What fish do you have it looks like possible attack by a fish

 

[Joker79]

I have 4 clowns, a scopas tang, a hi-fin goby an a pistol shrimp that's all. Lol. I believe the tentacles I've seen are from a micro brittle star.
I looked in the tank with a flashlight and all I've seen that was different are peanut worms, pods and the tentacles.

Unless you are blasting them with flow I dont think that could be the problem. Mine move all over the place and love it. I would think fish or creature. I would watch at night to see if anything is eating them. Other than that its kinda weird to lose them in that matter. Unless there have been some crazy swings in your system

I have heard of scopas tang going rouge on coral before...
