Thin white worm biting my zoas, plus other pests?

[Erik the Red]

Hey guys,

I’ve had these small zoas for a couple of weeks in my new tank. They’ve been dipped with “the dip” by fauna marin and then inserted in the aquarium. After a day, they started thriving and some polyps doubled already in size. However, its been a few days since many polyps haven’t opened that often, so this afternoon I’ve been looking closer to the zoas. I saw a thin white worm, coming out from the frag and bite a polyp (I swear it did bite because the polyp was pulled towards the worm).

moreover, it looks like there are a few things hanging off the zoas as well as a sign of what it looks like a bite.

could you help me to understand what is it? As soon as i see the worm again, I’ll take a video.

In the meanwhile, I will dip the zoas again...

You mean those tiny white points?
I though they were bigger...

in any case the dip killed only two amphipods

The white spots kinda look like hydroids to me. I don’t see any evidence of nudibranchs there
