Style Themes for Big Tanks
Big tanks = big creative freedom. Try one of these looks:

Maintenance Tips for Large Tanks
Big tanks are easier to balance but still need care. Here’s how to stay on top of it:
- Feed fish once or twice daily (don’t overfeed!)
- Change 20–25% of the water every 2 weeks
- Clean the filter monthly or as needed
- Check water temperature and pH regularly
