A couple of weeks ago, I went collecting for stonerollers about 30 minutes
from my house. I found some, along with some nice orangethroat darters for
someone I promised colorful darters to. Its possible they are rainbows, but
I don't think so.

I have collected at this creek, but I've never taken anything home from that
creek before.

While we were collecting, I noticed a few dead minnows here and there in the
creek, which I attributed to some yahoo on an ATV - there were fresh tracks
in the creek.

Anyway, I have had these fish about 2 weeks and I have just started losing a
couple of them. I have kept them at about 50 degrees since collection. They
have seemed to eat alright.

Tonight, while cleaning the tank, I noticed one male darter swimming very
badly. He was still rather vigorous, but he swam in very sharp circles.
pretty much like a pomeranian chasing its tail.
His colors were a bit washed out, but there were no obvious lesions on his
body. I think I saw a couple of clear bumps on his side. I killed him and
flushed the body.

I have never seen anything like this. ANyone have any ideas?
