Chiloglanis neumanni
Also known as: Neumanni Chiloglanis, Neumann's Suckercat
Origin: East Africa (fast-flowing streams)
Chiloglanis neumanni is one of several small torrent-adapted mochokids in the genus Chiloglanis, characterised by a greatly modified suckermouth that allows the fish to maintain position on smooth rock surfaces in powerful river currents. It is native to fast-flowing streams in East Africa and requires exceptionally well-oxygenated water to thrive.
In the aquarium it is best maintained in a dedicated setup replicating its native microhabitat: smooth flat rocks, very high flow rates from powerful circulation pumps and cooler, oxygen-saturated water. It is a peaceful, active grazer that will continuously work over rock surfaces consuming algae, biofilm and diatoms.
This species should be kept in groups of four or more; solitary individuals become stressed and may decline rapidly. It is not suitable for standard community aquariums due to its specialised requirements.
Water: 20–25°C, pH 6.5–7.5, soft to moderately hard (GH 4–14, KH 2–8); very high dissolved oxygen essential. Tank: 60 L minimum; smooth flat rocks; very high flow; no fine substrate that would clog gill rakers. Feeding: Biofilm and algae on rocks supplemented with sinking algae wafers, zucchini and spinach. Breeding: Not documented in captivity; presumed adhesive egg depositor on rock surfaces. Compatibility: Peaceful with other small rheophilic species; incompatible with low-flow community setups.
