Croaking Gourami (Trichopsis species)

The Dwarf Gourami male rivals the Betta for bright coloration, and its red and neon blue markings become even more intense at breeding time. In this and other Gourami species, the pelvic fins are elongated and threadlike. The fish use them to explore the surrounding environment. Dwarf Gouramis reach only about 2 inches in length.
