The Microctenopoma ansorgii, also known as the Ornate Ctenopoma or Orange Ctenopoma, is a captivating small freshwater fish native to the Congo River basin. These fish are related to the more familiar Spotted Climbing Perch but have a distinct appearance with elongated, rounded bodies and striking red and black striped fins. Their colors intensify when they are displaying, and black bars become visible on their bodies.Key Characteristics:
- Labyrinth Fish: Like bettas and gouramis, they possess a labyrinth organ that allows them to breathe air directly from the surface, which is beneficial in low-oxygen conditions.
- Size: They typically reach about 7 cm (2.4 inches) in length, with dominant males potentially growing slightly larger.
- Behavior: Ornate Ctenopomas are generally peaceful but can be shy and easily outcompeted for food by more boisterous tank mates. They are known to be territorial, particularly toward other fish with similar behavior.
- Habitat: They inhabit slow-flowing forest streams with dense vegetation, preferring stained water and plenty of hiding places.
Care Guidelines:
- Tank Requirements: A densely planted aquarium with ample hiding places, such as caves and driftwood, is crucial. Floating plants can help create a subdued atmosphere and provide areas for potential breeding. A securely covered tank is essential as they are known escape artists. A 60-liter tank is sufficient for breeding, but a larger tank is recommended for a community setting.
- Water Conditions:
- Temperature: They thrive in warm water, ideally between 26°C and 28°C (79°F and 82°F).
- pH: Maintain a slightly acidic pH between 5.5 and 7.5.
- Hardness: Soft to moderately hard water (5-20 dH) is suitable.
- Water Changes: Regular water changes of 20-30% are recommended to keep the water clean.
- Filtration: Peat filtration is beneficial.
- Diet: Ornate Ctenopomas are primarily carnivorous, feeding on worms, insect larvae, and other aquatic invertebrates in the wild. In the aquarium, they prefer small frozen or live foods like bloodworms, brine shrimp, and mysis shrimp. They rarely accept dried foods.
- Tank Mates: Choose small, peaceful species that occupy different water levels, such as hatchetfish, lampeyes, corydoras, and small loricariids. Keeping them in a species-only tank is also a good option. The presence of smaller dither fish can encourage them to be more active. Avoid keeping them with aggressive or overly active fish that may outcompete them for food or bully them.
- Reproduction: Breeding is possible but can be challenging. They are bubble nesters, with the male building a nest among floating plants. Soft, acidic water is necessary for successful spawning. It's best to remove the parents after the eggs hatch as they may predate on the fry.
Overall:Microctenopoma ansorgii are beautiful and fascinating fish that are relatively rare in the aquarium trade. While they can be a bit challenging to acclimatize, they are hardy once settled and can live up to 5 years. Providing them with the right environment and diet will ensure their health and well-being.
