Black bubble above closed zoa? What is it?

Hard to see but looks like bubble algae to me. Could be irritating the zoa so it's closing up.

If it is bubble algae, DO NOT POP. You will release spores into the tank.

Suction it out using a siphon tube. If it doesn't come out, you may have to cut it. If so, keep the siphon going while you do to be sure spores don't escape into the tank.

I'm pretty sure the release of spores when popping bubble algae has been debunked. Idk, maybe it's still debatable though.

Pic very blue and fuzzy to confirm but may be volonia or even sponge. Please repost under bright white lighting

It's valonia.

If you are able to grab it gently, wiggle & twist it off carefully, the bubble comes right off with ease. Remember, gently & without too much pressure. If it’s to difficult, I would do it outside the tank in a container, submerged in water, if the frag is removable. A fox face or emerald crabs are great at keeping that type of algae under control

Perhaps, but why not play it safe?

I realize that and fixed it- stupid spell correct always kicks in. After 40 years, I hope I know what it is

Zoa is now open and blocking the bubble should I Pursue it or leave it be?

if you can remove the frag, take the zoa out and get a pair of pointy tweezers or dental pick and scrape it off out of the tank

if you can not remove the frag, my recommendation would be to scrape it off in the tank.

the only evidence I have that this works - I received two frags of candy cane, and within a month the rock they were glued down on was almost covered by the bubbles. no other bubble algae in my tank. I scraped them off, and they didn't come back. if your tank is not "primed" to grow bubble algae, if you pop a single bubble, I highly doubt (that is the only evidence I have) you would start an infestation

Lets not over-react.

If it were my tank, I'd let it be and monitor.

If you see it beginning to spread, then relocate the coral with the bubble algae attached to an outside tank, and remove the bubble algae there. Then perhaps a coral dip of some kind (will someone chime in here with a recommendation please?), and return to the tank.

Keep it simple-
This is easier than it sounds : Take a 3/8" tubing and rubber band a small needle onto the end of tubing. start a siphon with tube and puncture the bubble and you will at the same time siphon any spores and put an end to issue and allow zoa to claim their real estate.
This should be a 5 minute process.

This isn't brain surgery. Pull the frag out, gently pry away/remove the bubble and place frag back. It should take all of 15 seconds. Wear some goggles and gloves or don't squirt yourself with zoa juice.
