Description

Black-winged hatchetfish has a convex body. It has a very deep ventral profile with its anal fin set back. This species has wing-like pectoral fins that often extend to half of the fish's body length. In general, coloration is silver with black patches and stripes but, depending on the angle of light, colors may vary. A stripe that is usually gold stretches horizontally from the gill cover the base of the tail. Black-winged hatchetfish can reach up to 2.8 cm (1.1 in) in length.

Distribution and habitat

Black-winged hatchetfish live in the calm streams and pools of the Orinoco and Negro region in South America.

Diet

Black-winged hatchetfish are omnivorous. They can be fed live as well as flake foods. In the wild, they feed mainly at the surface for insects, but can also eat crustaceans.

In the aquarium

Black-winged hatchetfish are peaceful fish that will do well with many other types of tropical fish such as smaller species of catfish and tetras. Make sure that there are small floating plants. Cover every hole at the top of the aquarium because in the wild, hatchetfish catch insects by jumping out of the water. Blackwinged hatchetfish inhabit the top of the aquarium.

Microctenopoma ansorgii is a small freshwater fish, known in the aquarium trade as the ornate ctenopoma, orange ctenopoma, ornate climbing perch, pretty ctenopoma, or rainbow ctenopoma. It is related to the more familiar spotted climbing perch, but looks very different. Its body is more elongated and rounded, with fins with red and black stripes; the color intensifies when the fish are displaying, with black bars becoming visible on the body. The ornate ctenopoma spawns at night, laying its eggs on a floating bubble nest like its relatives in the osphronemidae. It lives in the slow-flowing forest streams of the Congo Basin, where it feeds on worms, insect larvae, and other aquatic invertebrates. It is the most common member of its genus in the aquarium trade, where it is known for being a shy, easily bullied fish that needs live or frozen foods and which benefits from the presence of smaller dither fish to encourage it to come out of hiding.
