Hey, got these things popping up all over our 55gal reef and we're wondering what they are and if they are good or bad?
They look almost like small clusters (the size of a dime or smaller) of light blue eggs, but sometimes they have small hair-like things sticking out of them. Have done some searching but "little blue egg-like things" doesn't turn up much haha. Just wondering if anyone could shed some light? Thanks,
Dave
