Additional Information
Miscellaneous Information:  I bought these guys as a spawning pair.  They spawned once for me, but because I haven't been feeding as heavily as I should lately and have been making a lot of changes they haven't spawned since.  I forgot to take pictures of the newly hatched fry and didn't have the rotifers for them so they died.  I'll try again once things settle down a little bit.  Sorry for the poor quality pic.
