Serpae Tetra

The Serpae Tetra, also known as the Red Tetra, is a popular aquarium fish known for its vibrant red coloration and active nature. It is a hardy species that can thrive in a variety of tank setups and is often seen in community aquariums. The Serpae Tetra is an excellent choice for aquarists who want a colorful, peaceful fish with a bit of personality.

Scientific Name:

Hyphessobrycon eques (Serpae Tetra)

Maximum Size:

• The Serpae Tetra grows to a maximum size of 2 inches (5 cm) in length.

• While not overly large, they are still substantial enough to be seen in a school of fish.

Native Region:

• The Serpae Tetra is native to South America, specifically the Amazon River Basin, found in Brazil, Peru, and Colombia.

• These fish are typically found in slow-moving rivers, streams, and swamps, often in heavily vegetated areas.

Diet (Carnivorous or Omnivorous?)

• Omnivorous, meaning the Serpae Tetra will eat both plant-based and animal-based foods.

• In the wild, their diet consists of small invertebrates, algae, and decaying organic matter.

• In captivity, Serpae Tetras thrive on:
  ✅ High-quality flake food or small pellets formulated for omnivorous fish.
  ✅ Frozen or live foods such as brine shrimp, daphnia, bloodworms, and cyclops.
  ✅ Vegetables, including blanched spinach, zucchini, and peas.
  ❌ Avoid overfeeding, as it can lead to water quality problems and obesity in fish.

Lifespan:

• Serpae Tetras typically live between 3-5 years in captivity when given proper care. Some may live even longer with optimal tank conditions.

Breeding Season & Behavior:

• Egg layers, meaning Serpae Tetras lay eggs that are fertilized externally.

• They typically spawn in the early morning or late evening, where females release eggs, and males fertilize them.

• The eggs generally hatch in about 2-3 days, and the fry become free-swimming after another 2-3 days.

• Breeding season can occur year-round, but they are most active during the warmer months.

• To breed them successfully, it's recommended to have a separate breeding tank with soft, acidic water and plenty of fine-leaved plants or spawning mats for egg deposition.

Best Tank Mates:

Serpae Tetras are generally peaceful fish but can be a bit fin-nippy, especially when not kept in large schools. Therefore, they are best kept with other peaceful species that are not slow-moving or have long fins.

✅ Other peaceful tetras (Neon Tetras, Ember Tetras, Rummynose Tetras)
✅ Small catfish (Corydoras, Bristlenose Plecos, Otocinclus)
✅ Small peaceful cichlids (Apistogramma, Rams, Dwarf Cichlids)
✅ Small peaceful livebearers (Guppies, Platies, Endlers)
✅ Small shrimp (Cherry Shrimp, Amano Shrimp)
✅ Small snails (Nerite Snails, Mystery Snails)

🚫 Avoid:

• Long-finned fish (such as angelfish or bettas) since Serpae Tetras may nip at their fins.

• Aggressive species (like larger cichlids or predatory fish) that could harm or eat the Serpae Tetra.

Ideal Tank Conditions:

• Tank Size: A 10-gallon tank is sufficient for a small school of Serpae Tetras, though a 20-gallon or larger tank is preferable for a group.

• Temperature: 74-82°F (23-28°C), which is ideal for these tropical fish.

• pH: 5.5-7.5 (slightly acidic to neutral).

• Water Hardness: Soft to moderately hard water is best.

• Filtration: Moderate filtration is recommended to maintain water quality, but avoid strong currents, as Serpae Tetras prefer calm water.

• Décor:

  • Use live plants (such as Java Fern, Anubias, or Amazon Sword) to provide cover and natural shelter.

  • Fine gravel or sand substrate works best, as sharp objects could harm the fish.

  • Driftwood, rocks, and floating plants help to replicate their natural environment and provide hiding spaces.

⚠ Important Notes:

• Serpae Tetras are generally hardy, but they do best in stable water conditions with regular water changes.

• They should always be kept in schools of at least 6-8 fish, as they are a schooling species and feel safer in groups.

• Despite their peaceful nature, they can become fin-nippers, especially when not kept in schools, so always ensure that they have plenty of companions of their own kind.

• Overfeeding should be avoided as it can lead to digestive issues and poor water quality.

• Serpae Tetras are generally not prone to diseases, but maintaining good water quality is key to keeping them healthy.
