Origin

The Black-Banded Leporinus is native to various rivers in Central and South America, including the Amazon River, the Orinoco River, and the Rio de la Plata. Its coloration may vary depending on the specific habitat.

Lifespan

With proper care, the Black-Banded Leporinus (Leporinus fasciatus) can live for over 5 years.

Description

This fish is not ideal for beginners. The Black-Banded Leporinus can nip at other fish’s fins, is known to jump out of the tank, and can grow up to 8-12 inches (~20 to 30cm) in length. It has teeth, so handle with care. The bands on its body change as it ages. As a juvenile, it has 5 bands. By the time it is one year old, the first band splits into two, and every six months, another band will split. By three years old, it will have developed 10 bands.

While aquarium décor is optional, adding driftwood or bogwood can enhance the tank's appearance. Plants can be added, but they may be damaged by this fish, so proceed with caution.

The water must be well-oxygenated, so position filter outlets towards the surface. Use a secure lid, as the Black-Banded Leporinus may jump out of the tank. Maintain high water quality by performing regular water changes, cleaning décor, and promptly removing uneaten food to prevent decay and water contamination.

These fish are best kept in groups, but a small group may lead to squabbles. In smaller tanks, it’s better to keep just one specimen to avoid conflicts.

Food

The Black-Banded Leporinus primarily eats plant-based foods. It will take algae flakes and wafers but prefers fresh vegetables like cooked peas or lettuce. While it mainly eats plants, it may also accept bloodworms and brine shrimp. Avoid feeding meaty foods as they can be difficult to digest. Although they are primarily herbivores, they may prey on smaller tank mates if kept with them.

Sexing

Determining the sex of Black-Banded Leporinus is challenging until they reach maturity. At this stage, females tend to be larger and have a rounder body shape compared to males.

Breeding

Little is known about the breeding habits of Black-Banded Leporinus. They rarely breed in captivity, but they are known to be egg layers.
