I purchased 8 green neon tetras, and a few of them have developed specks of brown/white on their fins (see attached picture, there's a brown spot near where the dorsal fin attaches to the body).
Since its not just white spots, I'm guessing it's not ich. The 2 other green neons have a spot or two around where the caudal fin attaches to the body. All water conditions seem to be normal (pH 6.7, dH 3, ammonia 0, nitrite 0, nitrate 0) Water temp is around 78 deg F.
Any idea of what this could be?
