I will have to hit our local fish sotre and get some formalin (or
chemical supply house)

The cory we found was actually on the Amazon not the Negro. Has a line
down the body.  I will show you pictures, originally Karan and I were
debating on the boat between hastatus and pygmaeus.  Any help on IDing any
of these guys is greatly appreciated.  I have one roll of film ready to
develop and will work on another as soon as work gives me time to be home.

I think we may have had one Hemigrammus stictus, it had a cherry red
peduncle spot, I will have to recheck.

Thanks Again,
Kathy
