Aquariums

An aquarium is like having a piece of the ocean or a river in your home. Aquariums can hold fish, plants, snails, and other water creatures. Setting up an aquarium takes some work, but it is very rewarding. Watching fish swim in a beautiful tank can make anyone feel calm and happy.

Types of Aquariums

There are two main types of home aquariums: freshwater and saltwater. Freshwater tanks are easier to set up and take care of. Saltwater tanks can hold more colorful fish but need more work. Some people even set up tanks with just plants and no fish, called planted tanks.

Keeping an Aquarium Healthy

A healthy aquarium needs a good filter, the right temperature, and regular water changes. Fish make waste that can build up and make them sick. Changing about 25 percent of the water each week keeps things clean. Testing the water regularly helps make sure it is safe for the fish.
