Slow or no flow, humic water of the cypress swamp are indicators of acidity and hardness at the medium level, changes can be caused by different types of soils. The look of the biotope formed by peat and sand substrate of dark color, rows of vertical aerial roots of swamp cypress and dense thickets of marsh plants that can survive the dry season. As inhabitants a few medium-sized species of fish and crabs can be mentioned, who peacefully co-exist in different layers of the biotope. Between the leaves and stems of plants there are tiny Elassomas and Heterandria formosa searching for small live food, the more massive Jordanella floridae eats algae closer to the surface, and the dwarf marsh crabs are looking for food on the bottom, among the fallen branches and foliage.

Africa

1. South shore of Lake Chad near the village of Sangaria

Vera Gladyshenko (Saint Petersburg, Russia)

Aquarium Volume: 140 l

Aquarium Age: 5 months

Animals: Hemichromis bimaculatus, Polypterus senegalus

Plants: Ceratophyllum demersum, Nymphaea lotus, Juncus and Cárex (instead of Cyperus papyrus and some others)

Biotope description: Chad is a very shallow lake with a very flat bottom (and its surface is not constant). Even in the greatest flood its depths never exceed 4 meters. Once in the basin of the main tributary of the Shari there is heavy rainfall and the river brings a lot of water to the lake, Chad immediately grows, flooding vast areas of flat low-lying coasts. And during the low water in Shari, the lake level is lowered and the area gets quickly smaller. Despite of these metamorphoses, the lake is the only large body of water in Central Africa. The water in different parts of the Lake Chad has different mineralization: in most parts it is salted, and fresh near the mouths of rivers. Scientists explain lower mineralization of water by the constant change of water in the lake due to the outflow of the lower layers of water to the underground. The western and southern shores are low, swampy and covered with dense vegetation, northern and eastern ones are cut up. There are many sandy islands formed by flooded dunes here. The most common species of water plants are Cyperus papyrus, Aeschynomene elaphroxylon, water lilies and reeds, Ceratophyllum demersum. The bottom is mostly sandy with silt brought by the waters of the Chari.
