Alestopetersius caudalis, also known as the Yellow-Tail Congo Tetra, is a small, peaceful freshwater fish from Africa. It's ideal for community tanks with other peaceful species.
Overview
Alestopetersius caudalis, commonly known as the Yellow-Tail Congo Tetra or Caudalfin Tetra, is a small, peaceful fish originating from the rivers of Central Africa. These fish are distinguished by their shimmering bodies and vibrant yellow tail fins, making them a beautiful addition to any aquarium. They typically grow to a size of 5-6 cm and thrive in community tanks with other small, non-aggressive species.
Tank Requirements
The Yellow-Tail Congo Tetra requires a well-maintained tank of at least 60 liters. The ideal water temperature should be between 23-27°C, with a pH range of 6.0-7.5 and water hardness (GH) between 5-15 dGH. A densely planted tank with open swimming spaces and gentle water flow will mimic their natural habitat and keep them comfortable. Regular water changes and a quality filtration system are crucial for maintaining water quality.
Feeding and Diet
In the wild, Alestopetersius caudalis is an omnivore, feeding on small invertebrates, plant matter, and algae. In an aquarium setting, they will accept a variety of foods, including high-quality flake food, micro-pellets, and live or frozen foods such as brine shrimp and daphnia. A varied diet will help maintain their health and vibrant coloration. Feed them small portions 2-3 times a day.
Care and Maintenance
Caring for the Yellow-Tail Congo Tetra is straightforward, making it suitable for both beginners and experienced aquarists. Regular maintenance includes weekly water changes of 25-30% and monitoring of water parameters. Ensure that the tank has sufficient plants and hiding places to reduce stress and encourage natural behavior. Regularly check for signs of disease or stress, and take immediate action if any issues arise.
Compatibility
The Yellow-Tail Congo Tetra is a peaceful species that does well in community tanks with other small, non-aggressive fish. Suitable tank mates include other tetras, rasboras, and peaceful bottom-dwellers like Corydoras. They should not be kept with larger or aggressive species that may cause them stress or harm.
Breeding
Breeding Alestopetersius caudalis in captivity is possible, though it can be challenging. A separate breeding tank with slightly acidic water (pH around 6.5) and a temperature of 25-27°C is recommended. These fish are egg scatterers, so it's important to provide fine-leaved plants or a spawning mop to protect the eggs from being eaten. Once the eggs are laid, the adults should be removed to prevent them from eating the eggs. The eggs typically hatch within 24-36 hours, and the fry can be fed infusoria or finely crushed flake food until they grow large enough for more substantial food.
