Build Your Own Betta Aquarium Tank Kit

Build Your Own Betta Aquarium!

Betta splendens, also known as Betta or Siamese Fighting Fish, are among the most popular freshwater fish for home aquariums. Known for their vibrant colors and unique tail and fin shapes, this spunky fish is full of personality and is one of our favorite "pets." They are very hardy, which sadly makes them one of the most neglected fish, but they deserve proper care, starting with the right tank setup.

Our Build Your Own Betta Aquarium Kit is designed for hobbyists of all levels and lets you create the perfect home for your Betta fish. Start your next Betta aquascape today and give these beautiful fish homes that are safe, attractive, and suited to their needs. Learn more below!

We recommend floating aquarium plants, but for extra backup and safety, a proper aquarium lid helps keep your Betta secure. These spunky fish are skilled acrobats and known to jump — Betta to be safe than sorry! Living in a cooler area? Bettas do best in warmer water, so be sure to maintain a consistent, comfortable temperature of 76-80°F.
