That is interesting...these fish were caught out of a little pond up on the front of my place. Its about 40' x 80' and (must be) spring fed. There is no water shed nor runoff to/from the pond. I recently purchased the property - it has been fun seeing "what all is in there"...including these guys + the (1) big bass in the other picture. I have been thinking about throwing in Channel Catfish and feeding them out for fun.

Just for my learning purposes, how does "reverting back" happen?
