I was just down at my lfs and they had one tank full of angelfish and two of them were laying their eggs and fertilising them on the back wall of the tank, occasionally they would leave the eggs one at a time to chase the other angels to the otherend of the tank. Then suddenly all the other fish simultainously swooped on the eggs and ate them all. I was concidering buying the pair. They were $32NZD for the pair of them. It was fascinating watching them. Yeah, just thought you would be interested!
