Yes! Those are damsel eggs, 3 years ago I think (IIRC) when I had my 29 gallon tank, I bought 2 damsels and I put a tile in the tank hoping my paid or tomato clowns wOuld lay on it, the anemone moved and then the damsels took over the tile, 6 months later, I was in the tank cleaning going to remove the tile, I pout my hand in, and when I noticed these white dots on the tile I wondered what it could be, then it dawned on me, damsels eggs. They laid a batch about the soar of a quarter and did this EVERY Tuesday. They are amazing breeders if in the right conditions, unfortunately, they aren't valuable, hard to raise, and not worth it to raise either, lol.
They need a supers all rotifer and they call those the SS strain, it's a hard one to find and only a few have them, they are captive made to be smaller and are the only things that will successfully raise these fry.
These guys are pretty easy to get breeding, I wasn't even expecting mine to start breeding and boom, they did, keeping them well fed, healthy and fat is the key though, the fry make good coral food!
