I know this is prolly not possible but during my water change today I noticed my two yellowtail damsels obsessed with a spot on the underside of a rock inside a crevasse. They were fanning it and every couple of seconds one would swim upside down over the spot and I think I saw a black tube like thing sticking out. When I shined a light I could see tiny gelatin bubbles on the spot. Am I crazy or could they have laid eggs? That would be pretty cool, it would mean that I must be doing something right.
