Ornate Ctenopoma - Microctenopoma ansorgii : Complete Fish Profile & Care Guide
Table of contents
Introduction
The Ornate Ctenopoma (Microctenopoma ansorgii) is a captivating and relatively uncommon species within the aquarium hobby. Renowned for its stunning array of colours, this African anabantoid fish is highly coveted by enthusiasts. While sociable in nature, the Ornate Ctenopoma can thrive in a community tank, provided that appropriate tankmates are carefully selected.
Maintaining these fish in pairs is advisable. Although males may exhibit aggression and territorial behaviour, particularly during spawning conditions, cohabitation can be successfully achieved when ample hiding places and obstructed lines of sight are incorporated into the aquarium setup. While a species-only aquarium would be ideal, suitable tankmates can be introduced. Optimal companions include small, peaceful species that occupy the upper and lower regions of the tank, such as Tetras, Rasboras, killifish, and Hatchet fish. The presence of compatible tankmates encourages the Ornate Ctenopoma to venture out more, counteracting its inherent shyness. It is important to avoid housing them with diminutive fish or fry, as they may become prey, and aggressive or larger species prone to nipping or boisterous behaviour should also be avoided.
Creating a well-established aquarium environment for the Ornate Ctenopoma involves incorporating a dark substrate and abundant hiding places comprising plants, driftwood, and smooth rocks. Floating plants can serve a valuable role in diffusing light and instilling a sense of security for these timid fish. Adequate filtration with gentle water movement is recommended, and regular small partial water changes are essential to maintain low nitrate levels. The Ornate Ctenopoma displays adaptability to a range of water conditions, provided that extreme fluctuations are avoided. However, optimal colouration and vibrancy are typically observed in soft, slightly acidic water conditions. Adding dried Indian Almond leaves, or other suitable leaf litter further enhances the natural aesthetics of the aquarium.
The Ornate Ctenopoma has a rounded and elongated brownish body, exhibiting colour changes reflective of its mood. These variations can include hues of orange, green, or a combination of all three. Notably, six vertical dark stripes traverse the body, extending into the dorsal and anal fins, with interstitial regions displaying red colouration. The remaining fins are transparent, except for the dark brown caudal fin. During the breeding period, overall body colouration becomes more vibrant and pronounced, indicating the readiness to reproduce.

Sexual Dimorphism
Distinguishing between the male and female Ornate Ctenopoma is generally uncomplicated. However, males exhibit discernible characteristics that set them apart from females. Typically, males are larger in size and display a more striking colouration, particularly accentuated during spawning periods. Notably, males feature white edging and elongated tips on their anal and dorsal fins. Additionally, orange colouration is often observed along their flanks, contributing to their overall vibrant appearance.

Natural Habitat
The Ornate Ctenopoma is an enchanting fish species native to the remarkable waterways of Africa. Journey to the Chiloango River and the Aruwimi River in Angola, as well as the Ubangi River in the Democratic Republic of Congo, where these fascinating creatures call home. These fish are also present in Lake Mai Ndombe, the Luilak River, and the middle Congo River, where they gracefully navigate the currents.
Within these slow-flowing waters, the Ornate Ctenopoma thrives in warm and slightly acidic conditions, braving the challenges of low oxygen levels. Their natural habitats come alive with the beauty of lush marginal vegetation, providing a stunning backdrop for these captivating fish.
Breeding
Breeding Ornate Ctenopomas requires a degree of dedication and careful setup, but with appropriate measures, it can be successfully accomplished. A separate breeding tank should be established, characterized by subdued lighting and abundant vegetation, including floating plants. The water parameters in this tank should be maintained at relatively soft and acidic levels to encourage spawning. Conditioning the fish with a varied diet of live foods is essential in preparing them for breeding.
Once the fish are primed for spawning, the male will construct a small, loosely formed bubble nest composed of larger bubbles amidst the floating vegetation or beneath a dense leaf. The actual spawning event takes place beneath this nest, following the typical anabantoid embrace. A single spawning may yield several hundred eggs. It is crucial to promptly remove the female once all the eggs have been laid, as the male assumes a vigilant guardianship role over the nest and eggs. He will diligently tend to the nest and provide protection until the eggs hatch.
Upon hatching, which typically occurs approximately 24 hours after spawning, the fry will enter a free-swimming phase within two to three days. Given their minuscule size, the fry should initially be nourished with infusoria during the first week. Subsequently, they will progress to accept microworms and baby brine shrimp as suitable food sources.
Considering the territorial nature of the parents and the delicate nature of the fry, it is advisable to remove the adult fish from the breeding tank once the eggs have hatched. This ensures the fry's safety and optimal development while allowing for effective management of the breeding environment.
Diet & Feeding
The Ornate Ctenopoma's dietary preferences encompass various live and frozen food options. They readily consume nutritionally beneficial offerings such as bloodworms, white mosquito larvae, vitamin-enriched brine shrimp, and daphnia. Additionally, these fish may accept freeze-dried alternatives like krill. However, it is important to note that Ornate Ctenopomas are unlikely to consume dried foods such as flakes or pellets. Consequently, excluding these types of food from their diet is advisable to prevent unnecessary pollution within the aquarium.
