Distichodus Affinis

Distichodus affinis is a mid-sized Distichodus from the lower Congo River and its tributaries, presenting a sleek, compressed silver body with faint vertical banding visible particularly in juveniles. It is smaller and less boisterous than the popular D. sexfasciatus, making it a more manageable choice for home aquarists.

Like all Distichodus species, D. affinis has a primarily herbivorous diet and will graze on aquatic plants in the aquarium. Robust Java fern, Anubias species, or artificial plants are recommended for planting, as softer-leaved species will be consumed. The species appreciates moderate water flow and clean, well-oxygenated conditions.

Distichodus affinis can be kept in groups, which reduces inter-individual aggression and promotes natural behaviour. It mixes well with larger African tetras, robust catfish, and medium cichlids. Long-lived in suitable conditions, this is a rewarding species for a dedicated African river biotope.

Water: Soft to moderately hard, pH 6.0–7.5, temperature 23–27°C, GH 2–15, KH 1–8. Tank: Minimum 100 L with robust or artificial plants and moderate flow; cover the tank well. Feeding: Herbivore; algae wafers, blanched vegetables, plant-based flake, and occasional frozen foods. Breeding: Rarely bred in home aquaria; soft acidic water and large space needed for natural spawning. Compatibility: Peaceful with larger tetras, robust catfish, and medium cichlids; avoid delicate plants.
