I dont have a video but my dragonet was doing a odd behavior by vertically hitting the top of my aquarium over and over again. I did medicate the tank with chemiclean but I am using a airstone to keep oxygen levels fine. I did see on the reef2reef that they do this when mating. But I only have 1 and also its dorsal fin was fully extended when this was happening and I have never seen it fully extended. If anyone has any clue please let me know!
