A successful aquarium starts before the first fish enters the tank.
Choose an appropriate tank size
Research the adult size, behaviour and group requirements of the fish you want to keep.
Set up filtration
A suitable filter supports water movement and biological filtration. Filter capacity should match the tank and stocking level.
Cycle the aquarium
New aquariums need time to establish beneficial bacteria that process waste. Adding fish too early can expose them to harmful ammonia and nitrite.
Test the water
Use appropriate tests for parameters relevant to your setup.
Research compatibility
Temperature, water chemistry, adult size and behaviour all matter.
Species-specific requirements vary widely. Use reliable husbandry sources and seek specialist aquatic advice when needed.
