Aquarium fish and plant care
A stable aquarium needs more than clean water. Fish need suitable conditions for feeding and everyday activity, while aquatic plants need enough nutrients to retain their colour and grow evenly. Proper aquarium fish and plant care makes it easier to monitor water quality, meet the needs of your fish and keep the tank environment balanced.

Choose care products around your aquarium's needs
Every aquarium has a different fish population, mix of plants and water conditions. When choosing products for aquarium fish and plant care, start with the specific area that needs attention rather than adding treatments without a clear purpose.
- Water care: Choose products designed to prepare and maintain suitable aquarium water, particularly when changing water or setting up a new tank.
- Fish care: Match food to the species, size and feeding habits of your fish. Feeding an appropriate amount also helps reduce uneaten food collecting in the tank.
- Aquatic plant care: Choose plant nutrition according to the amount of vegetation, growth rate and tank layout, making nutrient dosing easier to control.
For aquarium care, Tetra is a practical brand to consider when you want to organise water, fish and plant care around the needs of your tank.
