Sounds like Columnaris which is a bacterial infection.
It's contagious so you want to take immediate action to save the rest of your fish.
Treatment for Columnaris:
>Do a 30-40% partial water change with a good quality declorinator.
>Turn the temp down to 76
>Increase areation
>Treat entire tank with Maracyn and Maracyn-two used concurently, OR Kanamycin
>Add salt, (sodium chloride, regular table salt without additives. Aquarium salt will work as will Kosher salt from the grocery store) Disolve it first and add it gradually over a 24 hour period)
>Feed sparingly during treatment.
Sorry for the loss of the two fish, hopefully the rest will be fine. Please post back with any additional questions or concerns.
