I couldn't find any really good web-sites that had pics of various species of the Myleus genus. I figure you piranha guys must know of a few characin sites . One site I visited claims there are over 29 species in this genus but didn't have any pictures . I had 5 red-hooks from a local fish store and just bought 5 more from a fellow hobbyist who ordered them from Peru. They appear to be slightly different but I'd like some pics to compare them to. Any help would be appreciated. Thanks in advance.
