Tentacles from my birdsnest??

[flatreefer]

Hello all

I've had this Colony of sour apple birdsnest in my tank for 2 weeks now,

I has been happy the whole time even through the minor alk swings I had until I got my doser dialed in,

Today over half of the poylps have been retracted, and I noticed 2 weird long tenacle looking things coming out of the one tip of the colony

Wondering if anyone has experienced this or knows what it is?

And FYI the colony came with the missing tissue your seeing in the back of the picture, it has been slowly growing back, then today it looked ticked off allday and I noticed the weird tentacles things

What maintenance activity have you done this past week?

The only thing I did was install a doser to maintain alk so I didn't have to hand dose,

This is the first time I've seen this boring worm type thing and the first time since I placed the coral in that it's been retracted so I'm lean towards that this boring worm of some sort is causing it,

I tool out the colony cut the peice with the worm thing off and superglued the end of the cut to be sure

I hope that I got him out

So you took the colony out.... cut on it...glued it.... and now wondering why the polyps to this animal/coral has retracted?

No,

I noticed all day that the coral wasn't opening its poylps.

Upon observation I noticed something I have never seen before, see picture,

After reading/researching I determined it was a boring spionid worm,

After more research/reading I found that the best method to remove this worm was to cut off the peice it's hosting or glue the hole in the coral it has made shut,

thats what I did.

I didn't frag the colony and wonder why poylps were retracted,
