About
Walk into Crowned Aquatics in Johnston, Iowa, and the first thing you'll notice is how clean the tanks are. Not chain-store clean — genuinely pristine, with healthy fish moving through well-maintained systems. Owner Justin has built something special in the Des Moines metro, a shop where the livestock is treated like it matters and the customers are treated like neighbors.
The freshwater selection is the main draw. Reviewers rave about quality bettas kept in proper tanks rather than sad little cups, vibrant rummy-nose tetras that thrive after purchase, and hard-to-find species that rotate quickly once stocked. Justin's live plant knowledge runs deep — customers switching to planted tanks consistently praise his ability to recommend the right species for specific setups.
When an ich outbreak hits your aquarium, he knows exactly which treatment to reach for. The shop also carries saltwater fish, and at least one longtime customer credits Crowned with a full tank relocation. What sets Crowned Aquatics apart isn't just the inventory — it's Justin himself.
He remembers returning customers by name, even after an 18-month absence. He'll spend real time walking through your questions, whether you're troubleshooting a disease or building out a new tank. If he doesn't stock something, he'll place a special order.
Multiple reviewers describe him as genuinely invested in their success as fishkeepers, not just in making a sale. Beyond the aquatics, the store carries reptile supplies (and crickets), driftwood, rocks, and quality dry goods. Moe, the resident giant iguana, has become a bit of a local celebrity — kids love him.
There's a laid-back, welcoming atmosphere that keeps people coming back weekly. For anyone in the Johnston or greater Des Moines area keeping freshwater or saltwater tanks, Crowned Aquatics is the kind of independent shop that earns fierce loyalty. The stock moves fast, so timing your visits after new shipments is worth the effort.

Customer reviews
“Great experience, have used them multiple times for fish and aquarium needs. Super friendly and helpful for new aquarium owners just trying to figure it out.”
— Bryan Reiter5.02 weeks ago“Great place to shop. I highly recommend”
— Adam Satterfield5.02 weeks ago“This is my favorite fish store in the metro! Justin is very knowledgeable and friendly. All the animals are very well taken care of and the tanks look great! I’ve never seen any sick fish in there when all the chain stores always have ich and all sorts of crud. He can order most anything you would need. I enjoy going in just to experience the calm vibes of the place and talk to Mo, his giant iguana. My daughter loves walking around and taking pictures of the fish (I added a picture she took). There’s also a Pokémon Go stop here, so if you’re kid is like mine and wants to play, perfect! Highly recommend Crowned!”
— Shaye Chatham5.02 weeks ago“Will always come to support my favorite fish store. Justin is always so friendly and can answer any questions I have. I’ve had a few tanks over the years and have always gotten my fish from them. Knowing the fish are high quality and are taken care of. All of my fish are happy and healthy from Justin. Remember to shop local people!”

— Desirae Leinen-Jenkins5.02 weeks ago“Justin at Crowned Aquatics has completely changed the game for me as a fish owner in all the best ways. When I had an ich outbreak, he knew exactly what products to use. When I was looking for something specific that he did not carry at the time, he would make a special order. When I decided to switch to live plants, he knew each type of plant and what would benefit me the most in my setup. Crowned is literally one of a kind in all the best ways possible. Its ALWAYS my first stop, either picking up crickets or a new addition to the tank.”
— Tanner Joe5.02 weeks ago“I’ve been using Crowned for the last few years as I’ve expanded my tanks at home. Justin always answers my numerous questions and takes the time to help me understand what I’m doing. I’m always happy with the quality of the plants, fish, and products I come home with!”
