well, my two cents....
i personally only do the hybrid "thing" with my orchids... as fer critters, i stick to species... i understand there is a place for hybrids because of varied interests, but i also just think about those goofy bubble-eyed goldfish and am reminded that the hybridizing can go too far!
by the way, vicious, do you actually have one of those gouramis?? and, isnt the species name osphronemus (spelling ?)? i have seen a few in stores before, but were alot smaller... have never actually seen a mature one in person....
