I slowly noticed over the past week that our black Kuda isn't using his tail to hold onto things like he used too. Yesterday I noticed about a 1/4" of the tip of his tail is white. Still eating good, just not using his tail & I can't see any wounds or parasites other than the white tipped tail & a kink at the base of the tail under the pouch. I know I read about this before but with this ongoing blonde moment I'm having I can't remember it or find it. Wasn't there a list of seahorse diseases & treatments?
