The red piranha in the aquarium

The red piranha is a fascinating and unique species of freshwater fish that is kept in many aquariums around the world. In this comprehensive blog article, we will take a closer look at the characteristics, needs and care of this fascinating creature.

Appearance and behavior

The red piranha, also known as Pygocentrus nattereri, is known for its striking red coloration and sharp teeth. These fish can reach a size of up to 30 cm and are known for their aggressive behavior. They should therefore always be kept with care in the aquarium and should not be kept with fish species that are too small or weak.

The red piranha is a schooling fish and should therefore be kept in a group of at least six animals to allow them to display species-appropriate social behavior. They can display their natural behavior in a well-structured aquarium with plenty of hiding places. They are territorial and defend their territory vigorously against intruders.

Setting up the aquarium

In order to keep a red piranha in a species-appropriate way, the right aquarium set-up is of crucial importance. An aquarium with a capacity of at least 300 liters is required to provide enough space for these active fish. The water should have a temperature between 24 and 28 degrees Celsius and a pH value in the neutral to slightly acidic range.

The aquarium should be equipped with sufficient hiding places such as caves, roots and plants to provide the piranha with places to retreat to. It is also important that the aquarium is well filtered, as piranhas eat a lot and the water can quickly become polluted. Regular water changes and good water quality are crucial for the well-being of the fish.

Nutrition and feeding

The red piranha is a carnivore and feeds mainly on live or frozen food such as fish, shrimp and mussels. It is important to offer them a varied diet to ensure they get all the nutrients they need. There are also special piranha foods on the market that contain additional nutrients and vitamins.

Feeding should be regular and in appropriate portions. It is important to ensure that all fish receive sufficient food and that overfeeding does not occur, as this can lead to health problems. Observe the eating behavior of the piranhas closely and adjust the feeding accordingly.

Breeding and reproduction

Breeding red piranhas in the aquarium is extremely difficult and requires special conditions. It is recommended to contact experienced breeders or aquarists for further information and instructions on breeding. In the wild, piranhas spawn in shallow areas of water during the rainy season. It is very difficult to mimic these conditions in an aquarium.

Problems and diseases

As with many fish species, red piranhas can also be susceptible to various diseases and health problems. Poor water quality, overfeeding, stress or socialization with unsuitable fish species can lead to health problems. It is important to carry out regular water parameter tests and act immediately if there are signs of illness.

Some common problems that piranhas can face are parasite infestations, infections, skin problems and digestive disorders. If a disease is suspected, it is advisable to ask a specialized veterinarian or an experienced aquarist for advice.

The Pygocentrus nattereri summarized once again

The red piranha is undoubtedly a fascinating species, but one that requires an experienced hand in the aquarium hobby. However, with the right preparations, a suitable keeping environment and a balanced diet, you can have a lot of fun keeping these unique fish. Remember that piranhas are predatory fish and should be handled with care. Observe their behavior closely and make sure they have optimal conditions to live a happy and healthy life.
