Additional Information
This pair is coming from Kevin Kohen at Diver's Den. Here is the link, although I'm not sure how long it will remain active:

This is the pair that I got from Diver's Den:

Not the best pic but the female is definitely gravid.

On December 7, I came home to find this:

There has been some confusion in the past about sexing these fish. They are sexually dimorphic, meaning that there is a difference between the sexes. All of the information that I was able to find states that the male is the one with the orange coloration. My findings show the opposite. The coloration of the juveniles should be very interesting to see.

Spawn number 2 occured on 12-19-10 between 4pm and 5:30pm. This was larger than the first. The pipe where they are located is a 2" pipe.
