All of sudden just now, all these worms (not sure which type) are sticking their heads out of the rocks and squirting some red liquid into the water column. I don't know what this is and i've never seen it before. They're all doing it at once. All the fish and coral seem fine, but I'm a little uneasy.
Is it poisonous? Anyone else know what's going on?
