Description

Adults reach a length of 5-6 cm. In the course of evolution, the fish has acquired a unique flattened body shape, which helps it withstand strong currents and stay on the surface of slippery stones. The coloration is inconspicuous brownish with areas of lighter shades – disguise on a sandy-stony bottom.

Behavior and Compatibility

Gastromizon of the Nan River is a territorial fish. However, he prefers to be in the company of relatives, provided that everyone finds a site for himself at the bottom of the aquarium.

It is peaceful, but due to the nature of the content (strong current), the number of compatible species is limited.

Maintenance and care, arrangement of the aquarium

The optimal size of the aquarium for 4 fish starts from 80 liters. Bottom area is more important than tank height. The decoration is simple and consists of coarse sand, pebbles, massive boulders and stones. It is permissible to place several natural snags on the substrate.

Many aquarium plants do not tolerate strong currents well and are unable to root in soft sand. If desired, you can use aquatic mosses and ferns, fixed on the surface of stones and snags, without the need for planting in the ground.

An important condition for the successful maintenance of Nan River Gastromisons is the provision of clean water with a minimum content of organic waste, as well as the presence of a moderate or strong current. Both tasks are designed to cope with a productive filter, for example, a system of one or two internal filters. They will not only become a guarantee of clean water, but also ensure proper internal flow.

Do not neglect the regular maintenance of the aquarium. In particular, weekly replace part of the water with fresh water, remove accumulated waste and carry out preventive maintenance of equipment.

Food

In nature, they feed on a layer of algal film that forms on stones, and the organisms inhabiting it. In the home aquarium, food with a high content of herbal ingredients, such as spirulina and similar ingredients, should be fed. A good choice would be special briquettes, pastes, tablets that can be fixed at the bottom without fear that they will be carried away by the current.
