While cleaning out my filter today, I noticed that one of my neon tetras has a whitish patch on his back around, but not on, the dorsal fin.
Anyone know what this could be?? Parameters are normal for this 20 G tank (0,0, and 10), and fish is acting fine so far. The tank's been running for 5 months, and I've had the neons about that long as well.
