Ctenopoma Acutirostre

Ctenopoma acutirostre is perhaps the most immediately recognisable African Anabantoid available in the hobby, presenting a striking cream-to-beige body covered in irregular dark brown spots that closely mimic a water-sodden fallen leaf. This camouflage is functional — this species is a sit-and-wait predator that drifts motionlessly among vegetation before striking at passing small fish with explosive speed.

In the aquarium, Ctenopoma acutirostre excels in a well-planted Congo biotope with dense mid-water vegetation, dim or plant-filtered lighting, and peaceful but large enough tankmates that will not be consumed. It is a labyrinth fish and must have access to warm, humid air above the waterline. A partially covered tank with a small air gap at the top is ideal.

Feeding is best accomplished with meaty foods presented near where the fish is stationed: frozen bloodworm, live or frozen brine shrimp, and whole small feeder invertebrates. Dry foods are accepted by some individuals but live or frozen prey items produce the most reliable response.

Water: Soft to moderately hard, pH 6.0–7.5, temperature 23–28°C, GH 2–15, KH 1–8. Tank: Minimum 150 L, densely planted, dim lighting, good surface air access, peaceful large tankmates. Feeding: Carnivore; frozen bloodworm, brine shrimp, small feeder invertebrates, and floating carnivore pellets. Breeding: Bubble nest builder; soft acidic water; male constructs surface nest; female removed after spawning. Compatibility: Predatory toward small fish; peaceful with medium to large peaceful species.
