A friend of mine had a opaline gourami for about a year and suddenly it seemed as if it were literally shrinking in size, and the coloration was pitiful, it had been in a 10 gallon moved to a 29 then back to the 10 and had been in the 10 for about 5 months. When we found it dead it had little bumps on its body and where ever there were bumps it was red. They were like streaks, the skin had turned red in that area and it was outlined in white. Any Idea what this was and what caused it.
