Build Your Own Aquarium Kit – Betta Tank

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, these spunky fish are full of personality and remain one of our favorite aquatic pets.

Although Bettas are often considered hardy, that also means they are prone to neglect and are frequently kept in setups that aren’t the best for their needs. (And they deserve more!) A proper Betta aquarium starts with a setup that is correctly sized, balanced, and designed with their comfort in mind.

Our Build Your Own Aquarium Kit – Betta Tank makes it easy for hobbyists of all levels to create the perfect home for a Betta fish. Start by selecting your aquarium, then build from there with substrate, filtration, lighting, and optional accessories. Each step features curated products to ensure compatibility, beautiful design, and most importantly, long-term health for your Betta.

A minimum setup includes: Aquarium + substrate + filtration + lighting

These core items are the bare essentials for a proper betta tank. From there, customize further with accessories, live plants, and more to support enrichment and overall health.

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.
