I bought 3 Madagascar Rainbows a few weeks ago. 2 of them have protruding vents ( about a week to 10 days later). It looks like a pinkish white ball on it's bum. It's almost as if their insides are turned hanging out. I have treated them for 5 days with Maracyn-2, but no luck. They are acting otherwise normal. Anyone know what this is ?
