About
William's Greenbank Aquarium is the kind of old-school, family-run fish store that earns loyalty measured in decades. Tucked into a convenient spot in Wilmington, DE, it's a place customers first visited as kids and still drive an hour from Maryland and New Jersey to reach. " The heart of the store is its enormous freshwater selection, which reviewers call the best in the area.
Hobbyists come here for the oddballs you won't find at the chains: leopard bush fish, green severums, blue lobsters, GloFish, and a healthy live-plant section for anyone scaping a freshwater tank. If you've been hunting freshwater shrimp for sale in Wilmington, DE, this is the spot — shoppers report their invertebrates arriving healthy and thriving. There's a saltwater side too, with marine fish that visitors consistently describe as clean and healthy, which earns Greenbank its standing as a genuine aquarium store rather than just another pet shop.
Beyond fish, the floor stays well stocked with axolotls, reptiles, and feeders. One recent visitor found crickets here larger and better priced than at other local stores, and another praised the team for going the extra mile to help rehome their RES turtles. Staff like Patrick get singled out for being genuinely kind and knowledgeable, happy to point you toward the right plants or talk through species pairing with zero pressure.
What hasn't changed is the experience: clean tanks, well-kept enclosures, fair prices, and free tips with every visit. For freshwater fish, axolotls, live plants, and aquarium supplies available in Wilmington, DE, Greenbank remains a local institution worth the drive.

— Mike Coop5.03 weeks ago“Nice store convenient location. Fully stocked. I visited for crickets which turn out to be a better priced item than other local stores and a little larger in size. Helpful and friendly service received. Actually had a snake out for viewing, holding and capture some photos. Decent prices on items I checked out. Store full of lovely fish tanks many many varieties available. Recommended this store, and you should visit. Glad I found it. What brought me in was the reviews I read when searching for local pet stores verses big chain stores. Impressed to read that they have been in business since the 80's. I will return for future services.”
