Pet Fish

Fish are known for their beautiful colors, unique patterns, and indescribable movements. Watching them swim and interact with each other can lower blood pressure and promote relaxation, NIH studies indicate.

Pet fish require less care and attention than other pets, such as cats and dogs. Setting up an aquarium can be costly initially, but the ongoing expenses are generally lower. However, knowing what your pet fish needs to thrive is important.

Aquarium fish are categorized based on their size and the type of water they can live in. Small fish, such as betta, guppies, and tetras, can be kept in small aquariums, while larger fish, such as goldfish, koi, and angelfish, require larger tanks and more space.

Fish require daily feeding and occasional tank maintenance. You must change the water regularly, clean aquarium filters and maintain the parameters as needed. Adding beneficial tankmates like mystery snails or nerite snails can help ease the burden of cleaning.
