urchin eggs

Hi everyone! I was looking at my tank (20L) and noticed my urchin had small opaque balls on it! Normally it’s tentacles are long and maybe there just bounces up right now? Please let me know what you think, because I’ve only seen pictures in here of males releasing sperm into the water! Thanks...

I have a long spine urchin, tuxedo urchin, various hermits, emerald crabs, snowflake eels, and file fish.
