Introduction: Meet the Otopharynx Tetrastigma, a stunning cichlid species known for its vibrant colors and striking appearance. Native to Lake Malawi in East Africa, this fish is admired for its shimmering scales that display a beautiful mix of greens, blues, and reds. The Otopharynx Tetrastigma is a favorite among African cichlid enthusiasts due to its relatively peaceful temperament and dazzling looks. Adding this species to your aquarium brings a touch of the exotic African waters to your home.
Scientific Name: The Otopharynx Tetrastigma is scientifically known as Otopharynx tetrastigma and belongs to the Cichlidae family. This species is often referred to simply as the “Tetrastigma Cichlid.”
Water Quality and Temperature: To create an ideal environment for the Otopharynx Tetrastigma, replicate its natural habitat with the following water parameters:
- Temperature: Maintain a temperature range of 76°F to 82°F (24°C to 28°C) for optimal health.
- pH Level: Keep the pH level between 7.8 and 8.6 to mimic their natural alkaline water conditions.
- GH Level: Aim for a general hardness (GH) level between 10 to 20 dGH for a stable environment.
- KH Level: Maintain the carbonate hardness (KH) within the range of 8 to 12 dKH.
Feeding: The Otopharynx Tetrastigma is an omnivorous fish with a varied diet. Provide a balanced diet that includes:
- Cichlid Pellets: High-quality cichlid pellets formulated for African cichlids.
- Vegetable Matter: Include spirulina-based foods or blanched vegetables such as spinach or peas to provide necessary nutrients.
- Live or Frozen Foods: Offer treats like brine shrimp, mysis shrimp, or krill to enhance their coloration and provide additional protein.
Tank Mates: Otopharynx Tetrastigma is relatively peaceful compared to other African cichlids but can become territorial, especially during breeding. Suitable tank mates include other mild-mannered cichlids from Lake Malawi, such as Aulonocara (Peacock Cichlids) and other Haplochromines. Avoid keeping them with overly aggressive or much smaller fish, as they may be harassed or outcompeted.
Substrates and Tank Decorations: The Otopharynx Tetrastigma thrives in a well-decorated tank that resembles its natural rocky habitat. Use a sandy substrate that allows them to sift through comfortably. Incorporate plenty of rocks and caves to create hiding spots and territories, which are crucial for reducing aggression. These structures also provide places for breeding and shelter, essential for their well-being.
Suitable Plants: While Otopharynx Tetrastigma is not known to be destructive towards plants, they might uproot them while digging. Choose hardy plants like Anubias, Java Fern, or Vallisneria that can be attached to rocks or decorations. These plants not only add to the tank’s aesthetics but also help mimic their natural environment.
Sexing: Sexing Otopharynx Tetrastigma is relatively easy. Males are typically larger and display more vibrant colors, with striking green, blue, and red scales, especially during breeding. Females are generally smaller and exhibit more subdued coloration, often with a more silver or grayish appearance. Males also have more elongated and pointed dorsal and anal fins.
Breeding: Breeding Otopharynx Tetrastigma in captivity can be a rewarding experience. These fish are mouthbrooders, meaning the female will carry fertilized eggs in her mouth until they hatch. To encourage breeding, provide a spacious tank with flat rocks where the male can court the female. After spawning, the female will carry the eggs in her mouth for about 3 weeks. Once the fry are released, they can be fed with finely crushed flake food or baby brine shrimp.
Maximum Size and Longevity: The Otopharynx Tetrastigma can grow up to 7 to 8 inches (18 to 20 cm) in length, making it a medium to large cichlid. With proper care, they can live up to 8 to 10 years, providing long-term enjoyment in your aquarium.
General Information: The Otopharynx Tetrastigma is a stunning addition to any African cichlid aquarium. Its vibrant coloration, combined with a relatively peaceful temperament, makes it a popular choice among aquarists. With the right care, this species will thrive and add a touch of Lake Malawi’s beauty to your home.
A Fun Fact: The name “Tetrastigma” refers to the distinctive “four spots” that can sometimes be observed on the body of these fish, although this feature is not always prominent in every individual. This unique characteristic is one of the many reasons why this species stands out among other cichlids.
