I am conerned about this zoa. Most polyps opening but often not completely. Tried new location but not better. today I noticed white mucous along many of the stocks. Tonight I looked more closely had can see this little black spots all over them. Any ideas of what this is and what to do? Worried about all of my new frags I just put in from the WWC live sale. Help!

Looks like black bugs. Remove and dip. See what happens.

Just dipped in coral rx. Tried scraping off what I could and shook vigorously. Definitely much less now. Is that a common issue? Will it spread to other zoa's?

Black bugs are a pest. Yes they can spread. Keep and eye on your other corals and dip as needed.

That absolutely looks like a pest of some sort, I would aggressively treat immediately with multiple dips. I also see that your zoas are stretched for light, which is a simple fix by giving them more par via moving them up or increasing the intensity of your light. If both of these issues are dealt with immediately, I think your zoas have a good chance of making a full recovery

After getting it back in the tank, it doesn't appear I got as much off as i thought. Will do again tomorrow.

I had moved the zoa's to the side and realized today they were stretching. I moved them back center after dipping and may move them higher after a day or two.

Any other dip I should try?

No. This is one from my lfs I got about 2 weeks ago. Don't want to infect my new ones though. Tempted just to toss it, but I need to learn how to deal with these types of issues.

If the Coral RX didn't shake them all loose and being that they are zoas, you might want to try a hydrogen peroxide dip. There are many threads on here with anything from a 10:1 to 1:1 water to peroxide ratio. Personally, I've typically used something close to 2:1 or 1:1 and have never had long term problems with the zoas.

I appreciate the help. I had quite the fiasco dipping! I took the zoa off the rock, put him in a cup with coral rx and let him soak for a couple minutes. I went downstairs to grab something and came back up to find our 55 pound puppy knocked the coral onto the floor spilling everything! I panicked since I just read about palytoxin. My dog was in the living room looking all innocent and guilty at the same time. I finally found the zoa on the rug under the dining room table. It didn't appear harmed, except for fibers it picked up from its travels. I redipped him, rinsed him and put him back in the tank. On Friday afternoon he opened up quite nicely, but still had some black spots. I did a hydrogen peroxide dip saturday morning. Today black spots are gone. About 75% of the polyps are opening so far. No other corals appear to be affected. Hopefully we are on the up and up. Thanks for the help!
