Aquarium Care basics
What do tropical fish need to stay healthy?
 
Tropical fish require consistent water temperature (typically 24–26°C), proper filtration and a balanced diet suited to their species.
How often should I change water in a freshwater tank?
 
Most freshwater tanks benefit from a 10–25% partial water change fortnightly to maintain stable water parameters.
Do I need a heater for my fish tank?
 
If keeping tropical fish, yes. A heater ensures stable water temperature, which is essential for immune function and digestion.
What is the nitrogen cycle in aquariums?
 
The nitrogen cycle is the biological process where beneficial bacteria break down fish waste into less harmful compounds, helping maintain safe water conditions.
