Tropical fish bring something truly special into a home gentle movement, bright colours, and a peaceful rhythm that’s incredibly calming. But while they look effortless, tropical fish rely on stable water, the right temperature, and proper care to thrive.
This UK focused guide walks you through everything you need to know to set up and enjoy a healthy tropical aquarium.
Tank Size Matters More Than You Think

Bigger tanks are more stable
Water stays cleaner longer
Fish experience less stress
For beginners, aim for at least 60–100 litres.
Heating & Temperature
