Description: An elongated fish with elaborate fins. The tips of the anal, caudal, and dorsalfins are elongated and pointed. The outer rays of the caudal fin form a 'lyre-tail' shape.  The background body coloration of malesis brownish-yellow to brownish orange. The body is marked with numerous red spots.  The fins are orange with a broad yellowand red border. The tips of the fins are white. The females are brown in color with a scattering of red spots.

Males are more colorful, have more elongated fins, and are slightly larger.

A breeding tank measuring 12" (30 cm) with a capacity of 2.4 gallons (9 L) is sufficient. Thewater should have a pH from 6.2-6.8, a water hardness from 2-6 dH, and a temperature from 73 to 77°F (23-25°C). Keepone female with two or three females. Use a spawning mop or fine leafed planted along with a peat moss substrate,if possible. The eggs are hung from plants around the tank. Each day, 10-20 eggs are produced, for a periodof 10-12 days. The peat (containing eggs) should be removed and placed in a separate rearing tank.  Replacethe peat moss in the spawning tank. The eggs hatch 10-12 days and once their eggs sacs are consumed, theycan be fed on roftiers and small nauplii.
