I had a scooter dragonet (synchiropus ocellatus) for about 2 yrs. now. Yesterday he seemed a little sluggish,but there were no white spots, or anything abnormal other than the lack of activity. This morning he was dead. Does anyone know the normal lifespan of these fish? I have been battling cyanobacteria for two weeks now,but everthing else is OK. Thanks for your help.
