not sure if it has something to do with the lunar cycle. i noticed mass congregations of my micro brittle star fish.. there were HUNDREDS of them in clusters all over the tank, climbing all over the corals, coming out of every nook and cranny. as i'm watching this thinking this is weird, i started seeing them, little "clouds" coming off of alot of them. never seen a spawning event like this in these guys. pretty cool. just curious if this is isolated, or if anyone else has witnessed this before.
