South America: Rio Truando, Columbia. Occurs in shallow water with dense vegetation.
General Body Form:
Streamlined with a deep, rounded anterior and long, muscular posterior. Fins are moderately long and rounded. Superior-facing mouth.
The base color of the body and head is golden-olive. The ventrum is bright silver. From their anal fins to their caudal fin, the fish have as series of 7 to 9 tiger-like black bars on their flanks. The black bands alternate with metallic gold bars. At the beginning of the dorsal fin, one bar widens into an oculus or wedge-shape that is rimmed by a bright gold ring. Fins are translucent olive-gray with a flush of pale gold proximately.
Easy. Sexual dimorphism: Males are smaller, more brightly colored and possess gonopodiums. Females are larger and fuller-bodied. Males perform a courtship display where they show the female the gold spots on their sides and then extend their fins as far as possible. The female then swims away if she's not receptive or she chooses her mate and allows the male to inseminate her via his gonopodium. Eggs are fertilized internally and develop over the course of a month. The fry hatch internally and are then are born 2 to 4 at a time over several days. Fry should be feed infusoria for the first few days, then the are able to eat the same diet as their parents. Fry are sexually mature at 3 months.
