Fishes are living, sentient beings – not works of art. Aquarium fishes are the most common pets; yet people often lack the knowledge and care to handle these fascinating creatures properly.

The 4 most important points to bear in mind when keeping aquarium fishes:

  • Fishes are enjoyed by people of all ages – yet keeping fishes is not child's play. Expertise is essential to ensure that fishes feel comfortable and do not suffer. Children up to the age of 14 should therefore be accompanied by a knowledgeable adult.
  • Some fishes defend their space and are aggressive towards other fishes. It is important to choose fish species that get on well with each other and to offer them all sufficient space, hiding places, and opportunities to keep busy.
  • Good water quality reduces the risk of disease and stress in the fishes. A suitable pH value for the fish species, low ammonia, nitrite, and nitrate levels and the right temperature are important.
  • Fishes are susceptible to various diseases such as fin rot, white spot disease, and fungal infections. Prevention, early detection, and expert treatment are essential. Regular water changes and a balanced diet contribute to the health of the fishes.
