HABITAT OF A SMALL CREEK
IN THE LOWER CONGO REGION
Biotope: this represents an authentic small river biotope of the lower Congo River. There lives a variety of beautiful fishes and also some smaller predators (such as Polypterus). Smaller cichlids, tetras, Synodontis and Gnathonemus species dwell over and under rocks, gravel and driftwood with interesting vegetation.
Fishes: Hemichromis species, Steatocranus casuarius, Syndontis decorus, Gnathonemus petersi, Polypterus ornatipinnis, Phenacogrammus caudalis, Pantodon buchholzi, etc..
Plants: the aquatic vegetation consists of Bolbitis and Anubia species, and most of those are rooted on driftwood and rocks near the edges of the creek, as decorated.
Décor: beige sand, some gravel and rocks (roundish), on which the Hemichromis started to lay eggs right away, just hours after Heiko had introduced them into their “home”.
Water parameters: The pH was 5.8, conductivity around 35 µS/cm, and the temperature between 27.5- 28.5 °C.
Sponsor: the aquarium, décor material, filter and heater were supplied by ZOO-ZAJAC, the fishes were specially imported for this exhibition by Aquarium Dietzenbach for Heiko Bleher.
