HYPOSALINITY Quick!
If the Hex is not already setup, set it up quickly as a hospital tank. Make sure the water is the same temp and PH as the tank that your fish is coming from. Place the fish in the hospital tank and over the next 2-3 days, start dropping the salinity levels in the hopital tank down to 1.009. Leave the saline level at that level for 4 weeks. If all is well then, slowly raise the salinity back up to normal levels. Continue to leave the fish in the hospital tank for another week. If all continues well, and your main tank has not been hit with ick [which is very likely that it will be unless you move all your fish to the Hex] then you can return your sick fish back home on the 5th week. Feed all fish garlic soaked food over the next week.
To do more research on this matter, including the hyposalinity treatment, use our search feature to study up on the subject of ICK.
Good luck, and keep us posted.
