You ever seen one of your fish pecking at them?

No but I do have a Coral Beauty.

You ever seen one of your fish pecking at them?

That was my first thought as well, they look like they're frequently trimmed or nipped at

By chance do you do regular water changes? I have seen this with some who don't do water changes and do not supplement trace, which is my second question. Not saying other things can be the issue, and sometimes light can be a factor, as well as nipping, mentioned above.

I do bi weekly water changes. I just starting dosing trace elements. Red sea AB+

I am curious also. My Pink Cadillac colonies have a few of these. I didn't give it too much thought, just figured it was a random growth mutation. Or it got physically damaged along the way.

I've had one acro that did this, was a small piece with a few branches. Then the tips turned to blobs like your picture, and now its regrowing new tips. As if it encrusted over itself.

I don't do water changes, but I do dose trace elements. I'm not sure that is related, I have tons of other acros that haven't done this.

could it be an acro bacterial infection? dont know much about it myself but have seen some threads talking about it https://www.reef2reef.com/threads/whats-going-on-with-this-acro-bubbly-tissue.665601/

I have lost about 4 colony's recently but none had the weird growth. I do think I have some bacterial thing going on in my tank as I have dipped them, put them under a microscope, used a magnifying glass, even had my son who has the best vision in my house look at them. I have yet to find flat worms or any bugs.
