I'm a biologist that recently visited Honduras doing some birding.  I also have a strong interest in North American native fishes.  I went snorkeling in a mountain stream at about 5000 ft. near Santa Barbara in northwestern Honduras.  This stream came right out of the ground in a large spring that was the water supply for the city of Santa Barbara.  The water was crystal clear and very cold and swift.  I dove in a small, fairly deep (5 ft.?) pool and lifted rocks on the bottom looking for fishes & freshwater crabs.  I soon found several catfishes that looked nearly identical to the Stonecat (Noturus flavus).  They varied in size from about 4 inches up to 10 inches.  The adipose fin was connected to the caudal fin just like in Madtoms.  They also had 3 or 4 randomly placed, very small brown pin-point type spots on the bodies of each individual.  They shared this stream with freshwater crabs and some type of fish similiar to a Goodeid.  The closest village to this site was called La Zona.  I would appreciate any information on the identity of this catfish.  Thanks!
