Gephyra dwarf cichlid

Apistogramma gephyra reaches 5-6 cm. The male has a silvery body with blue highlights, a pointed dorsal fin, and a slightly forked caudal fin. The female is smaller, pale yellow with a black stripe. This species is less colorful than other apistogrammas but very interesting behaviorally. It lives in pairs and defends a small territory. Breeding occurs in a cave; the female turns bright yellow and guards the eggs. It is endemic to the Rio Negro.
