" It could be Brooklynella or even possibly Uronema. I would hope for Brooklynella and treat it with a series of formalin dips. There is another disease that is common with Seahorses, but I can't remember the name of it right now. Unfortunately it is tough to treat. Just one more reason to quarantine all seahorses before adding them to the display. The Seahorse disease I am thinking of is very contagious and hard to beat. It wouldn't hurt to treat the fish with Nirtofurazone in quarantine and give it some 45 minute formalin dips to. Seahorses do pretty well in hyposalinity as long as you check the pH daily. Hypo with nitrofurazone and adding formalin dips would give you a three pronged attack. I would be adding some Beta glucan to the diet until the fish either recovers or dies. You can put some Beta glucan in the brine shrimp water 6 hours before feeding them to the Seahorse.
