General care guide: Fish & aquatics
Cycle first
Run your tank for 3–4 weeks before adding fish so beneficial bacteria can convert ammonia. Test water regularly.
Essentials
Filter, heater for tropicals (24–28°C), dechlorinator and a test kit. Feed small amounts once or twice daily and change 20–25% of the water weekly. Never release fish into the wild.
