Sabaleta/Rainbow Characin Rhoadsia altipinna

The beautiful, glistening Sabaleta (one of two South American fish with that name) is also called the Rainbow Characin and Rainbow Tetra.

It is native to slow-running streams of the lowlands on the Pacific side of southwestern Ecuador. Females grow to some 10 cm and males up to 17cm long.

Males have longer fins, including red-edged anal fins. They guard their nests and help with egg care.
