Paul,

interested to hear if your fish are still flashing?

Well, I've been busy and haven't done anything to the tank for a while--I
even allowed the water level to fall a couple of inches. For the most part,
the fish have been looking a bit better with one notable exception (a green
sunfish that mostly scrapes the same location but shows no sign of
parasites), which has now been released back to the wild.

However, yesterday, I vacuumed the gravel again and top the water level off.
Although it's not too bad, my large mouth bass are definitely looking a bit
more irritated than normal.
