What You Need to Start
Here’s a basic checklist to help you plan:
- Fish tank (5 to 20 gallons is a great size to start)
- Water conditioner (makes tap water safe for fish)
- Filter (keeps the water clean)
- Heater (for tropical fish)
- Gravel or sand (for the tank bottom)
- Plants or decorations (for beauty and fish hiding spots)
- Fish food
- Fish net and water test kit
Tip: Start small, but not too small. Tanks under 5 gallons are harder to keep clean.
