Mottled Ctenopoma Care Guide
Ctenopoma weeksii · Freshwater Fish

What Mottled Ctenopoma look like
Ctenopoma weeksii, commonly known as the Mottled Ctenopoma, exhibits a medium-sized, laterally compressed body that typically reaches a maximum adult size of 3-5 inches (7.5-12.5 cm). The species is characterized by its deep, irregularly shaped body, which is adorned with a dark brown mottled pattern that provides excellent camouflage against its natural habitat of decaying plant material. The skin texture is rough, contributing to its cryptic appearance. The fins are relatively broad and exhibit subtle banding, enhancing its ability to blend into the murky waters of the Congo. Notably, this species lacks pronounced sexual dimorphism, although males may display slightly more vibrant coloration during breeding. Defensive adaptations include its cryptic coloration and the ability to remain motionless among vegetation, evading potential predators.
Behavior & temperament
The Mottled Ctenopoma is primarily a solitary and cryptic species, preferring to dwell in the benthic zone of slow-moving waters. It exhibits a non-aggressive temperament, often relying on its camouflage for protection rather than confrontational behaviors. This species is not an obligate schooler, but it may be found in loose aggregations in areas with ample cover. During breeding, Ctenopoma weeksii engages in egg scattering, with females laying adhesive eggs among submerged vegetation. Their behavior is generally characterized by a calm demeanor, making them suitable for community tanks with similarly temperate species.
Diet & feeding
In the wild, the Mottled Ctenopoma is a carnivore, primarily feeding on small invertebrates and crustaceans. In captivity, it requires a diet rich in high-quality protein sources, such as live or frozen foods like bloodworms, brine shrimp, and small pellets designed for carnivorous fish.
