Maintaining the Aquarium
Regular maintenance is key to a successful aquarium. This includes:

1. Water Changes: Regular partial water changes help remove waste and maintain water quality. Aim for changing 10-20% of the water weekly.
2. Feeding: Overfeeding can lead to poor water quality. Feed your fish small amounts once or twice a day, and remove any uneaten food.
3. Monitoring Health: Keep an eye on your fish for any signs of illness or stress. Early detection can prevent serious problems.
