Good job Tony! I saw these white specks in person and I knew they looked familiar but I couldn't put my finger on it. I think they are nassarius snail eggs as well.
More food for your upcoming fishies. I'd just scrape them off the glass, but no need to take any particular action.
I've never had my nassarius lay eggs, but my cerith snails were laying eggs about every other day for a while, leaving those long spiral eggs tracks all over the glass and the rocks.
