About The Mad Jellyfish

​​​

The Mad Jellyfish is a freshwater aquarium store located in Chestertown, Maryland, offering a wide selection of live freshwater fish, aquarium plants, supplies, and accessories for both new and experienced fish keepers.

What started as an online aquarium business has grown into a full retail store where customers can browse our selection in person, ask questions, and find new additions for their aquariums. We also continue to serve customers online, making it easy to shop for live freshwater fish and aquarium products from home.

We carry a constantly changing selection of freshwater species, including angelfish, cichlids, tetras, corydoras, livebearers, catfish, loaches, goldfish, bettas, plecos, rainbowfish, and many other unique and popular aquarium fish. Our inventory changes frequently as new fish arrive, so there is always something different to discover.

In addition to livestock, we offer aquarium plants, fish foods, substrate, nets, filtration supplies, decorations, and other essentials to help customers create and maintain healthy freshwater aquariums.

Customers in the Chestertown area are welcome to visit our store and shop in person. Online customers can also order available fish and aquarium products through our website. Local pickup is available for customers who prefer to order ahead and collect their purchases at the store.

At The Mad Jellyfish, our goal is simple: provide healthy freshwater fish, dependable aquarium supplies, helpful customer service, and a growing selection for aquarium hobbyists of all experience levels.

We enjoy helping customers discover new fish, build thriving aquariums, and find species that are a good fit for their tanks.
