Introduction:

The Red Hook Metynnis, Myloplus rubripinnis, is a striking freshwater fish known for its brilliant red-tipped fins and round, silvery body. Often referred to simply as the Red Hook, this fish hails from the slow-moving rivers and tributaries of South America. It is a large, peaceful schooling species that is well-suited for spacious community tanks, making it a popular choice among experienced aquarists. Its vibrant coloration and dynamic swimming behavior add vitality to any aquarium setup.

1. Natural Habitat and Behavior

Native to the Amazon and Orinoco River basins, the Red Hook Metynnis thrives in calm, well-vegetated waters with soft, acidic conditions. They are herbivorous fish, often found grazing on plant matter along the riverbanks.
In the aquarium, Red Hooks are active swimmers and are best kept in groups. They are peaceful by nature but require a school of their own kind to feel secure and exhibit natural behaviors. When housed properly, they are dynamic yet serene additions to community setups.

2. Aquarium Setup

Tank Size: A minimum of 100 gallons is recommended due to their potential size, reaching up to 12 inches in length. Their schooling nature also necessitates a larger tank to accommodate their active swimming and social behavior.
Substrate: A soft sandy substrate is ideal, mimicking their natural river habitats. Gravel can also be used, but the substrate should be smooth to prevent injury as they are constantly moving around the tank.
Decor: Red Hook Metynnis appreciate an environment with plenty of open swimming space but also require some structure for security. Use driftwood, large stones, and hardy plants, though be cautious with live plants as these herbivores are likely to nibble. Floating plants can also help diffuse light and create a natural habitat.
Water Conditions: These fish prefer soft, acidic to neutral water with a pH of 6.0 to 7.5. Keep the water temperature between 75°F and 82°F. Filtration should be strong, as Red Hooks produce a significant amount of waste, and water movement can help replicate their riverine habitat.
Lighting: Moderate lighting is best for Red Hook Metynnis. Bright lighting can be stressful for them, so floating plants or diffused light can help create a more natural and comfortable environment.

3. Diet and Feeding

Red Hook Metynnis are predominantly herbivores and enjoy a plant-based diet. In the wild, they feed on a variety of plant matter, algae, and sometimes small insects.
In the aquarium, they should be offered high-quality vegetable flakes, spirulina pellets, and fresh vegetables such as spinach, zucchini, and lettuce. Supplement their diet with the occasional protein-based treat like bloodworms, brine shrimp, or daphnia to ensure balanced nutrition.
Feed them twice a day, providing enough food for the entire school while avoiding overfeeding, as this can affect water quality.

4. Compatibility with Other Fish

Red Hook Metynnis are peaceful and can be housed with other non-aggressive species. They make good tank mates for similarly sized South American fish such as large tetras, Severums, and peaceful Cichlids.
Avoid keeping them with smaller fish, as their size and activity can cause stress to more delicate species. Additionally, smaller fish may be seen as prey if the Red Hooks become large enough.
It's important to keep them in schools of at least five or more, as they rely on social interaction and feel safest in numbers.

5. Common Challenges and Tips

One of the main challenges with Red Hook Metynnis is their tendency to eat live plants. If you're aiming for a planted aquarium, choose hardy, fast-growing species, or opt for artificial plants to avoid frustration.
These fish produce a significant amount of waste, so strong filtration and regular water changes are crucial to maintaining a healthy environment.
Since they are large, active fish, ensuring they have adequate swimming space is essential for their well-being. Overcrowding or undersized tanks can lead to stress and health issues.

Conclusion:

The Red Hook Metynnis is a visually appealing, peaceful schooling fish that brings a sense of vibrancy to larger freshwater tanks. Its shimmering silver body, accented by its bright red-tipped fins, is a beautiful contrast to the greenery in a well-maintained aquarium.
While they require a spacious tank, good water quality, and a well-balanced diet, they are relatively easy to care for, making them an excellent choice for aquarists looking to expand their community tanks with a larger, dynamic species.
