Mikrogeophagus altispinosus (Mikrogeophagus altispinosus) – a freshwater fish from the cichlid family.


South America. Mikrogeophagus altispinosus lives in the quiet coastal zones of the Guapore and Mamore rivers in Brazil and Bolivia.

Characteristics and disposition

Bolivian nurses grow up to about 8 cm. Gender difficult to distinguish.

Adult male slightly larger with longer fins. In a mature female, a red color can be observed around the abdomen. During the spawning season, females are more rounded. Very calm fish, but it is inadvisable to keep more than a pair. The males start out into skirmishes over territory.

Nutrition and feeding

We feed a variety of dry, frozen and live food, supplemented with fruit or vegetables.


An aquarium of at least 80 cm in length will be suitable for a pair of cichlids, preferably with a sandy surface in which they can dig freely. Fish are quite shy and need hiding places made of stones, roots and vegetation. Lighting should be muffled by floating plants. They will feel much more confident in such a tank.

They easily adapt to all water parameters, but its quality is very important. They require frequent changes. Can be kept in a social aquarium with smaller peaceful fish.


Put a few flat stones into the spawning tank, on which the female will be able to spawn. We can encourage fish to breed by raising the water temperature to about 27-28 ° C.

Before the planned spawning, the fish should be fed abundantly with live and frozen food. The couple prepares the place for reproduction and the act begins. The female lays eggs in the line, which the male then fertilizes by flowing over them. This operation is repeated for about an hour during which about 200 grains are folded. Parents take care of the eggs.

The female fan with her fins ensures the supply of fresh and oxygenated water, and the male protects the area by chasing away other fish. Hatching takes place after 2-3 days. We feed the fry with small foods.
