Description
Red Fin Obliquidens – Haplochromis sp. #44
Introduction:
The Red Fin Obliquidens, or Haplochromis sp. #44, is a captivating and colorful African cichlid that makes a striking addition to any tank. Known for its vibrant red fins and distinct body shape, this species is highly sought after by hobbyists who appreciate their dynamic personality and stunning appearance. While not as common as some other African cichlids, it is admired for its eye-catching colors, especially when it displays its full red fin coloration. Reaching a maximum size of 6-8 inches (15-20 cm), the Red Fin Obliquidens is ideal for a large, well-maintained aquarium.
1. Natural Habitat and Behavior
The Red Fin Obliquidens originates from East African lakes, most notably Lake Victoria and surrounding regions. In the wild, it inhabits rocky and sandy areas, often found in moderate to deep waters. These cichlids are primarily found in rocky crevices, where they can establish territories and find food in the form of smaller fish, invertebrates, and plant matter.
This species is known for its territorial nature, especially during the breeding season. Males are particularly aggressive towards other males, and the red coloration of their fins is often a sign of courtship or territorial dominance. While they are not overly aggressive toward other species, they can become quite defensive of their space, making proper tank setup and monitoring important.
2. Aquarium Setup
- Tank Size: A minimum of 55 gallons (208 liters) is recommended for a single Red Fin Obliquidens. If keeping more than one or adding other African cichlids, a larger tank (75 gallons or more) is ideal.
- Substrate: Use a mix of sand and fine gravel, which simulates their natural environment. The substrate should be deep enough to allow for digging behavior, which is common in many African cichlid species.
- Decor: Provide ample hiding spots using rocks and caves. The Red Fin Obliquidens will often claim territories within the rockwork and will need these hiding spaces to retreat from other fish. An aquascape with plenty of rocky areas and open swimming spaces will help prevent aggression.
- Water Conditions:
- pH: 7.5–8.5 (alkaline)
- Temperature: 75–80°F (24–27°C)
- Water Hardness: 10–20 dGH (moderately hard to hard)
- Filtration: This species prefers well-oxygenated water, so a powerful filtration system is crucial for maintaining clean, high-quality water.
- Lighting: Moderate lighting is best to highlight the red coloration of the fins without stressing the fish.
3. Diet and Feeding
The Red Fin Obliquidens is omnivorous, and its diet should reflect the variety it would encounter in the wild. It thrives on a balanced diet that includes protein, plant matter, and algae.
- High-quality cichlid pellets or flakes (rich in protein)
- Frozen or live foods like brine shrimp, bloodworms, and daphnia
- Blanched vegetables such as zucchini, spinach, and peas
- Algae-based foods or spirulina to supplement plant matter
Feed your Red Fin Obliquidens 2-3 times a day in smaller portions to prevent overfeeding and ensure a balanced diet. A varied diet will promote healthy growth and vibrant coloration.
4. Compatibility with Other Fish
While the Red Fin Obliquidens is not the most aggressive African cichlid, it can become territorial, particularly during the breeding season. It is important to house it with tank mates that are similarly robust and can handle potential aggression. Ideal tank mates include:
- Other robust African cichlids, such as Mbuna or Victorian cichlids
- Larger species that can hold their own, like larger Synodontis catfish
- Species that inhabit different parts of the tank to reduce territorial overlap
Avoid small, peaceful fish that might be bullied or outcompeted for food. It is best to keep a single male with multiple females to reduce male-to-male aggression.
5. Common Challenges and Tips
- Aggression: Like many African cichlids, the Red Fin Obliquidens is territorial and can display aggression, especially during breeding. Providing plenty of rock structures, caves, and hiding spots will help create multiple territories and reduce conflict.
- Water Quality: Maintaining high water quality is essential for the health of the Red Fin Obliquidens. Regular water changes (about 25% per week) and good filtration are necessary to keep the water parameters stable.
- Breeding: Red Fin Obliquidens are mouthbrooders. During courtship, the male will display his red fins to attract a female. The female will carry the fertilized eggs in her mouth until they hatch, after which she will protect the fry until they are ready to swim.
Conclusion
The Red Fin Obliquidens is a stunning addition to any cichlid enthusiast’s aquarium. With its vibrant red fins and active, territorial nature, it thrives in a well-maintained, spacious tank. With proper care, including a suitable diet, tank mates, and environment, the Red Fin Obliquidens will reward its keeper with its bright coloration and dynamic presence.
