About Us

Welcome to MastahBetta’s online freshwater aquarium fish store! We are based in Honolulu, Hawaii and are open to serving and shipping to all of you on the Neighbor Hawaiian Islands and anywhere in the Mainland (excluding Alaska).

At our store, we are passionate about providing high-quality freshwater fish and aquatic plants to our customers. We strive to be the go-to destination for all things related to freshwater aquariums in Hawaii, and we take great pride in our extensive selection of fish and plants.

Our team is made up of experienced aquarium enthusiasts who are dedicated to ensuring that our customers have the best possible experience when shopping with us. Whether you are an experienced fish keeper or just starting out, we are always available to answer your questions and offer advice.

We understand that purchasing fish and aquarium supplies online can be daunting, which is why we go above and beyond to ensure that our customers have a smooth and hassle-free experience. We carefully package all of our fish and plants to ensure that they arrive at your doorstep healthy and happy.

In addition to our wide selection of freshwater fish and aquatic plants, we also currently carry a variety of fish foods that we also feed our fish in-house. We are constantly updating our inventory to ensure that we are offering the latest and greatest products to our customers. We hope to get more into aquarium supplies as soon as possible!

Thank you for considering our store for your freshwater aquarium needs. We look forward to serving you and helping you create the perfect underwater world in your home or office!
