 Brittlestar frenzy
I am fairly new to reef tanks and watched an amazing event this evening. I purchased my first toadstool leather and placed it in my aquarium. I scraped a small patch of green algae off the back glass. About 1 hour later 75 to 100 brittle starfish came out from the live rock. They were everywhere and tended to head toward various coral or shells. 4 of the largest stood up like a barstool, with all of the legs down and the body up in the center. They would release a white milky substance every minute or so. After about 15-30 minutes they all went back into the live rock but the water was a bit cloudy.
Is this the brittle star version of a salmon run. Was it a coincidence or did something trigger this amazing event?
