Mikrogeophagus altispinosus

Mikrogeophagus altispinosus or Bolivian sheepfish live naturally in the Amazon basin, South America. The fish can be found in small streams and backwaters of the Guaporé River in Brazil and the Mamoré River in Bolivia. The fish are not demanding and even novice aquarists can keep them.

The body of Mikrogeophagus altispinosus is oval. Fins pointed at the ends. Males compared to females more colorful and slightly larger. In addition, the fins of the males are longer. Male size reaches 9 cm, while females grow to 6 cm.

Mikrogeophagus altispinosus at a young age and especially when stressed, e.g. in a shop, may not be noticed due to its unassuming appearance. However, they can become one of the most attractive tropical fish in your aquarium when they mature and are well looked after. Mikrogeophagus altispinosus live longer and are more tolerant of a wide range of conditions than their more popular close relative Microgeophagus ramirezi. Mikrogeophagus altispinosus are generally fairly peaceful, provided they are kept in a common aquarium with commensurate size of peaceful fish, with very small fish may become food for them.

Keep Mikrogeophagus altispinosus recommended in pairs or singly in an aquarium volume of 100 liters. We recommend sand or fine sanded gravel as substrate. The fish are constantly digging for food particles in the substrate. Various plants can be planted around the perimeter of the aquarium, which are not disturbed by the fish. At the bottom should be placed set of shelters in the form of large stones, grottos, ceramic pots and snags.

Water parameters: temperature 22-26° C, hardness dH 5-12°, pH 6-7. Need quality filtration, increased aeration and a weekly substitution of 1/3 of the aquarium water with fresh. It is advisable to create a small water current in the aquarium.

Ambient, moderate light. This can be achieved by placing a few bushes of floating plants on the water surface, which act as a natural light filter. The light duration is 10 - 12 hours per day.

Bolivian sheep are omnivorous fish. In nature they eat small insects, plant seeds, fry and detritus. In an aquarium, the fish are fed with Artemia, Tubifex, chironomid, flake and pelleted food. Feed preferably in small portions 2-3 times a day.


Under suitable conditions, Mikrogeophagus altispinosus will spawn without any special measures for this. They spawn like many cichlid species, when a small area is prepared and cleaned, and then the female hatches eggs (up to 200 eggs) on the smooth wall of the shelter. Both parents take care of the eggs.

The eggs incubate for 2-3 days, and after a week the fry are swimming freely and eating. At this time they are fed live dust and after 7-10 days begin to give artemia. The parents take care of their young for a few weeks.
