Physical Characteristics of Rummynose Tetras

Size and Shape

Rummynose Tetras are small fish that typically reach 1.5 inches (4 cm) in length when fully grown. Their slender, elongated bodies help them move swiftly through the water, making them excellent swimmers. Their distinctive red snout is one of their most appealing features, and the coloration deepens in healthy fish, signaling good water conditions and nutrition.

Coloration

Rummynose Tetras are best known for their vibrant red snout and silver body. Their red coloration, which covers most of their head and extends slightly down their gill covers, is one of the most striking features of this fish. The rest of their body is a metallic silver with a hint of yellow, creating a beautiful contrast. The intensity of the red coloration can vary, often being more vivid in healthy, well-cared-for individuals.

Lifespan

With proper care, Rummynose Tetras can live up to 5 years or more. Maintaining a stable and appropriate environment is crucial for ensuring their long lifespan, and a balanced diet and routine maintenance will help them thrive.

Setting Up a Tank for Rummynose Tetras

To create the best environment for Rummynose Tetras, it’s important to understand their natural habitat and replicate it in your aquarium. Rummynose Tetras are native to the Amazon Basin, where they live in slow-moving, clear streams and rivers with a variety of plants, submerged branches, and soft, acidic water.

1. Tank Size

While Rummynose Tetras are small fish, they thrive in schools of 6 or more, so it’s important to choose a tank that provides adequate space. A minimum of 10 gallons (38 liters) is recommended for a small group of Rummynose Tetras. However, a 20-gallon tank or larger would provide more swimming space and allow you to keep additional species. A larger tank also ensures that the water parameters remain more stable, reducing stress on the fish.

2. Water Parameters

Rummynose Tetras are fairly sensitive to water conditions and require stable, high-quality water to thrive. These fish do best in soft, slightly acidic water, which mimics their natural environment.

• Temperature: The ideal temperature range for Rummynose Tetras is 75°F to 82°F (24°C to 28°C). Maintaining a stable water temperature is essential, as drastic fluctuations can stress the fish.

• pH Level: Rummynose Tetras prefer slightly acidic to neutral water with a pH range of 6.0 to 7.5. They do not do well in hard or alkaline water, so it’s important to monitor the pH regularly.

• Water Hardness: The ideal water hardness for Rummynose Tetras is between 2-10 dGH. Soft water is preferred, as it replicates their natural environment in the Amazon.

• Ammonia and Nitrites: As with all aquarium fish, ammonia and nitrite levels should be kept at zero to avoid toxicity. Ammonia and nitrites are harmful to fish, and their presence is an indicator of poor filtration or water maintenance.

• Nitrates: Nitrate levels should be kept below 20 ppm. Nitrate can accumulate over time, and high levels can lead to health issues for your fish. Regular water changes are key to keeping nitrates at safe levels.

3. Filtration System

A gentle filtration system is essential for maintaining water quality. Since Rummynose Tetras are native to slow-moving waters, they prefer tanks with low to moderate water flow. A sponge filter or a gentle hang-on-back (HOB) filter works well for these fish. Avoid strong currents, as they can stress the Tetras and make it difficult for them to swim.

4. Substrate and Decorations

For the substrate, fine gravel or sand is ideal for Rummynose Tetras. The soft substrate is gentle on their delicate fins and allows them to forage naturally for food. A darker substrate will also help highlight the beautiful colors of the fish.

Decorate the tank with live plants, such as Java Fern, Cryptocoryne, or Anubias, as these species provide shelter and hiding places for the fish. Adding some driftwood or roots will create natural hiding spots, and the tannins released from the driftwood can slightly acidify the water, which is beneficial for the Tetras.

5. Lighting

Rummynose Tetras prefer moderate lighting, which is consistent with the dimly lit waters of their natural habitat. A standard aquarium light on a 10-12 hour light cycle will be sufficient. Bright lighting can stress the Tetras and cause them to become less active.

6. Tankmates

Rummynose Tetras are peaceful and social, making them excellent additions to community tanks. They do best when kept in schools of 6 or more, and they are generally compatible with other small, peaceful fish. Some great tankmates include:

• Tetras: Other species of peaceful Tetras, such as Neon Tetras or Cardinal Tetras, make excellent companions.
• Corydoras Catfish: These peaceful bottom dwellers will not compete with Rummynose Tetras for space or food.
• Small Gouramis: Species like Honey Gouramis or Dwarf Gouramis can coexist peacefully with Rummynose Tetras.
• Livebearers: Small species like Platies, Mollies, or Endlers can also be kept with Rummynose Tetras.

Avoid keeping them with large or aggressive fish, as they can become stressed or even eaten. For example, avoid Cichlids or large barbs that may harass the Tetras.

Feeding Rummynose Tetras

Rummynose Tetras are omnivorous and will accept a variety of foods. A balanced diet is important for keeping them healthy and vibrant. A good feeding regimen includes both meaty and plant-based foods.

1. Staple Diet

High-quality tetra pellets or flakes formulated for small tropical fish should form the base of the diet. Look for products that contain essential nutrients such as vitamins, minerals, and proteins to ensure overall health.

2. Live and Frozen Foods

Supplementing with live or frozen foods like brine shrimp, bloodworms, daphnia, or blackworms is highly beneficial. These provide essential proteins and simulate the types of food Rummynose Tetras would encounter in the wild.

3. Vegetables

Although primarily carnivorous, Rummynose Tetras will also eat small amounts of plant matter. Offer blanched spinach, zucchini, or peas occasionally for variety.

4. Feeding Schedule

Rummynose Tetras have small stomachs, so they should be fed 2-3 times per day, with small portions that they can consume in a few minutes. Avoid overfeeding, as excess food can lead to water quality problems.

Breeding Rummynose Tetras

Breeding Rummynose Tetras in captivity is possible but can be a bit tricky. These fish typically breed in groups, so you’ll need a breeding tank and several individuals to encourage spawning.

1. Breeding Tank Setup

Set up a breeding tank with soft, acidic water (pH 6.0-6.5) and a temperature of around 80°F (27°C). Provide a fine-leaved plant, such as Java Moss, for the female to lay her eggs. A sponge filter is ideal for gentle water circulation.

2. Spawning Process

To encourage breeding, feed your Tetras a nutritious diet of live foods for several days before attempting to breed them. After several days of conditioning, the female will lay her eggs on the plants, and the male will fertilize them.

3. Fry Care

Once the eggs hatch (usually within 24-48 hours), the fry will need very fine food such as infusoria or liquid fry food. As they grow, you can start feeding them baby brine shrimp or finely crushed flakes.

Common Health Issues

Like all aquarium fish, Rummynose Tetras can be susceptible to certain health problems, especially if water conditions are not maintained properly. Some common issues include:

• Ich (White Spot Disease): This parasitic infection causes white spots to appear on the body. It can be treated with anti-Ich medication and improved water conditions.
• Fin Rot: Caused by bacterial infections, fin rot can lead to deterioration of the fins. Good water quality and antibiotic treatment are essential.
• Swim Bladder Disease: This can occur due to overfeeding or constipation and can cause the fish to float erratically. Fasting for a few days can help.
