I have had this guy for several months now. His name is "Jag", sometimes I call him other names because he keeps taking off filter tubes. He lives in a 75 gallon till I can afford to get a 125 or 150. From looking at pictures in my books, I think he might be crossed with losellei, not sure if right spelling on that. I like him because of his attitude and his size. He is around 14 inches and quite aggressive.
