Searched but didn’t see my particular egg situation. Noticed these while cleaning my Seachem Tidal filter. They may have been out of the water for a bit. Have them floating in an isolation box. Yesterday the eggs inside the sac were yellow today they look orange. There are approximately 6-10 eggs inside each clear egg sac. Tank inhabitants 40g breeder = 2 clowns, 6 Line Wrasse, green banded goby, nassarius, Trochus, a couple hermits bristle worms and micro brittle sea stars. All have been in there over a year. It was hell trying to get a photo and I had a filter on my phone

Cool - I haven't seen those before.

You can rule out the fish and the hermit crabs. My first thought is some sort of snail eggs - but Trochus are apparently broadcast spawners, and Nassarius lay more ribbon-shaped egg masses (according to Google). If your tank has good live rock in it, could these be from some other critter that you didn't identify?
