Frequently asked questions
What do I need to set up an aquarium?
The basics are a suitably sized tank, a filter, food and water treatments, plus a heater for tropical fish. Cycle the tank before adding fish so the water is safe.

Bigger tanks are more stable and forgiving for beginners, and stocking depends on the species. Research your fish's adult size and needs before buying.
