So I was looking at my fish tank, and there were 2 little neon yellow orbs floating around. They were about 3mm wide perfect spheres. Does anyone know what these are? Livestock list- 2 clownfish 2 yellow watchman gobys Pistol shrimp Fire shrimp Arrow crab Urchin Helmet crabs Snails Tail spot blenny Chalk bass Also, in the bottom corner of my 25 gallon reef tank, one of my clownfish was kinda spazzing out on the glass, vibrating its belly on the glass, then Attacking it with its mouth, then repeating. Are they breeding or what?
