I just saw an amazing thing! I upgraded my filtration system, on my eight gallon nano, from a small homemade cannister filter, to a Fluval 3 filter, and the added two gallon water change, plus extra current, brought around twelve small brittle stars out of hiding, and they all crawled up on top of the corals, stood on their tippy toes, and went through a breeding cycle! It was amazing! They all did it at the same time, and then crawled back under the rockwork!
No, I didn't have the camera ready! Sorry!
