About
Oak Park Natural Pet & Fish is a family-owned fish store on the border of Oak Park and River Forest that has built a loyal following among aquarium hobbyists across Chicago's western suburbs. Shoppers describe it as a true mom-and-pop staple for Oak Park and River Forest residents, with friendly, knowledgeable staff who are genuinely passionate about fish. The store keeps both freshwater and saltwater livestock under one roof, plus aquatic plants and a deep pet-supply aisle for dogs, cats, reptiles, and birds — but it's the aquarium side that draws people from well beyond the neighborhood.
The coral selection is a genuine standout. Regulars praise it as beautiful and fairly priced, which has made the shop a go-to for reef tank builders in the area. Reef keepers come for corals and saltwater fish for sale in Oak Park, IL — the kind of marine livestock that's hard to find outside a dedicated reef shop.
Freshwater hobbyists have their own draw: peacock cichlids, bettas, and live aquarium plants available in Oak Park, IL, with the bettas kept in their own planted, filtered tanks rather than plastic cups. What keeps people coming back is the hands-on help. Staff like Alex, Julian, and Jaz ask about your tank before recommending anything — one keeper was walked through using crushed coral to fix water hardness in a freshwater setup, and the crew once helped a customer move a 90-gallon aquarium into his home.
The shelves are packed with Hikari and Bug Bites fish food and supplies, and the team is happy to special-order whatever a pet needs. Prices are generally fair, first-timers and seasoned aquarists get the same patient attention, and reviewers keep calling this the kind of independent shop the chains can't match. For Oak Park aquarists who want real expertise and healthy livestock available locally, this aquarium store offers something a big-box retailer simply cannot.

Customer reviews
“Very friendly and helpful employees.”

— Teresa Capleton5.02 months ago“The place to go to get raw pet food”
— Timothy Koscal5.03 months ago“Great local pet store. For a small location, their selection of pet food/products is pretty expansive. Awesome showing of both freshwater and saltwater fish, as well as aquatic plants. The people working there are very friendly and knowledgeable.”
— Andrew Wheeler5.03 months ago“Wow! Have you ever watched an episode of hoarders? That's what this place is like. Mismatched dirty tanks, over stuffed shelves, trip hazards all over the floor (hoses, product, fans, etc.). One of the tanks had so many fish in it, I think if you put the net in you would catch 7 fish without moving the net. I've seen good reviews but after stopping here, I have no confidence the fish would live or could infect my tank. Shockingly bad.”
— Rick Eiseman1.03 months ago“Diamond in the rough in terms of customer service and rare finds. Store may be a bit crowded in the aisles but its has everything under the sun. And if not they always seem happy to order anything your pet may need. Absolute staple for the Oak Park and River Forest residents who own a dog or have a pet fish.”
