The home of the Maronibuntbarsche is in South America. The freshwater fish live in the Orinoco Delta and in the rivers of Guyana, Surinam and French Guiana.

The peaceful ornamental fish can be kept in small groups but also in pairs. Maroni cichlids are well suited as a beginner’s fish for beginners and can live up to 12 years with good care.

What distinguishes Maroni Cichlids?

Maroni cichlids only feel comfortable in the company of other calm fish. Ideal roommates are e.g. ornamental tetra, armoured catfish, discus fish or angelfish. Under no circumstances should the Maroni perch be kept together with aggressive or very lively fish species. These would only constantly disturb and frighten him, which would be detrimental to his life expectancy. However, the Maroni Perch can live well together with other peaceful and calm fish.

The appearance of Maronibarsch

The fish have an oval, high-backed, laterally flattened body. The basic colouration is light brown to cream. The fins are yellow-green or brownish throughout, in the rear part of the anal and dorsal fins are also greenish spots. From the upper side of the head to the lower end of the head an arched black stripe runs over the eye of the fish.

Below the last three hard fins there is also a clearly visible round black spot which extends downwards in a dark band. This is where its nickname “keyhole perch” comes from.

Sex differences

The males are generally slightly larger than the females. However, the sexes are hardly distinguishable in juvenile fish. In sexually mature fish, on the other hand, there is a visible distinction, the so-called genital papilla (sex opening).

In adult male fish, the anal and dorsal fins are also significantly longer than those of the females.

Water values for chestnut cichlids

Its natural habitat are rivers with soft, slightly acidic water. In an aquarium with the following water values, the chestnut perch therefore feels at home:

  • pH value: approx. 6.0-7.5
  • Total hardness: up to 5-20°dGH
  • Temperature: 22°-26°C

Food and nutrition for chestnut cichlids

The Maronibuntbarsch eats in free nature all kinds of small animals such as worms, crabs and insects. In order for the fish to thrive, live food should therefore preferably be given as well. However, it can also be fed with frozen and dry food for a change.

The ideal aquarium for chestnut cichlids

The aquarium for chestnut perch should hold at least 200 litres of water. For optimal keeping even tanks of 250 litres or more are recommended. The Maroni perch needs a lot of free swimming space but also sufficient hiding places by roots, stones and dense planting. Shading by some floating plants is also recommended. The substrate can consist of fine sand or pebbles. Maronibarsche do not belong to the burrowing fish species.

Housing conditions

Maroni perches develop under optimal husbandry conditions into stately fishes of approx. 10 – 12 cm in size. Below is a summary of the most important husbandry conditions:

  • Community tank
  • lush vegetation
  • enough hiding places
  • balanced nutrition from live and dried fodder
  • regular partial water change

Special features of chestnut cichlids

The fish species is extremely jumpy. It reacts to stress and strong anxiety with distinct colour changes. When it is startled, the Maroni bass changes its body colour from light brown to an intense dark brown covering its whole body. The brown tone lightens again as soon as the animals have calmed down.
