The name you probably found them under was 'gold colisa' - which is incorrect. They are gold three-spots (trichoagster trichopterus), a color morph of the 'blue' three-spot gourami. They can become very aggressive but you appear to be in luck as they seem to both be females. Males are more aggressive. Here are some pics that have been sexed of various three-spot color morphs. All are the same species so, besides color, they're identical in every way: http/www.aqualandpetsplus.com/Gouramis,%...ichogasters.htm
