What they're saying about us
We can tell you all day how great our stores and staff are, but we'd like you to hear from our customers...
“Aqua World has been a staple in our lives since moving to Wildwood in 1998. John, the owner, is extremely knowledgeable and has always been very helpful. Their fish quality is high ... we've never had any issues.”
Robin B.Hobbyist
“I personally had an amazing experience here. I saw other reviews saying the fish were priced higher. But probably for good reason. They seem to be very seasoned aquarists. It is definitely my go to place hereto.”
Zen D.Hobbyist
“This is the best spot for aquarists in St. Louis hands down. I have not bought fish food, fish, plants, or equipment from a chain store since I discovered this small mom and pop gem a few years ago!”
Angie RoederHobbyist
“Aqua World in Ellisville has been phenomenal is helping me get started with my aquarium. Stephanie has had a pivotal role in helping me with the care of my newly established (in 2014) tank and ongoing care since!”
Lucy G.Hobbyist
“This is probably my favorite place to have a pond build on your property or build it yourself. (DIY) John is the owner of this lovely relaxing business. All of the materials are top quality along with the amazing fish he has for your indoor or outdoor pond.”
