4. Epalzeorhynchos munense also known as the redfin shark, is a species of cyprinid fish found in the Mekong, Chao Phraya and Mae Klong rivers basins in Indochina. It resembles the rainbow shark (E. frenatum) and the two have frequently been confused (the name red fin shark has been used for both). Unlike other Epalzeorhynchos species, E. munense is believed to be rare in the aquarium trade and is not known to be bred in commercial farms.

Please note that while these fish are often referred to as “sharks” due to their shark-like dorsal fins and overall body shape, they are not true sharks. They are a type of cyprinid, related to carps and minnows.

Selecting the Right Aquarium

When it comes to housing Epalzeorhynchos, tank size matters. These fish are active swimmers and need ample space to move around. A tank of at least 30 gallons is recommended for one fish, with an additional 10 gallons for each extra fish. The aquarium should be wider than it is tall, as these species are known to swim more horizontally than vertically.

Creating the Ideal Environment

Epalzeorhynchos prefer a habitat that resembles their natural environment. They appreciate a tank with plenty of hiding places, so consider using rocks, driftwood, and aquatic plants to create a natural, river-like environment. However, ensure that the materials used do not have sharp edges as they could harm the fish.

The substrate should be soft, as Epalzeorhynchos species are bottom dwellers and often sift through the substrate. Sand or small, smooth gravel is ideal. They also prefer dim lighting, so consider using subdued lighting or providing plenty of shade with plants and decor.

Water Conditions

As tropical freshwater fish, Epalzeorhynchos thrive in warm, slightly acidic to neutral water. Maintain a temperature between 72 to 79 degrees Fahrenheit and a pH level between 6.5 to 7.5. Regular water changes are crucial to keep the nitrate levels low and maintain water quality.

Water Conditions: 72° to 80° F, pH 6.5 -7.6
Size: normally 6 inches.
Lifespan: 5-6 years
Diet: Omnivore

Feeding

Epalzeorhynchos are omnivorous and have a varied diet. Feed them high-quality flake food or pellets as a basic diet, supplemented with fresh, frozen, or freeze-dried foods such as bloodworms, brine shrimp, and vegetables. Avoid overfeeding, as this can pollute the water and lead to health problems.

Behavior and Compatibility

Epalzeorhynchos species are known for their territorial behavior, especially among their own kind. It’s advisable to keep only one Epalzeorhynchos per tank to avoid conflicts. They can cohabitate with other species that occupy different areas of the tank and are not too small to be seen as prey.

Healthcare

Epalzeorhynchos are generally hardy fish, but they are not immune to common fish diseases like ich or fin rot. Regular monitoring of fish behavior and water conditions is essential to detect early signs of illness.

Breeding

Breeding Epalzeorhynchos in an aquarium is extremely challenging, and there’s little documentation of successful captive breeding. Most Epalzeorhynchos sold in pet stores are wild-caught or bred in commercial farms using hormones.

In conclusion, Epalzeorhynchos are striking, active fish that can be a joy to keep in an aquarium. While they require some specific care requirements, their lively nature and fascinating behavior make the effort worthwhile. With the right care, these fish can live up to 10 years, providing a long-term companionship for the dedicated aquarist.
