Very sick tiger balms
 

Three of my daughters tiger balms had died with the same thing.
They break out with a whole in thier side. Does anyone know what this is, What causes it and what we can put in the tank. All the other fish have never been effected.

Just a thought, you might have better luck with this in the freshwater fish disesases section.
