Saltwater Fish

Old Town Aquarium offers the greatest diversity of saltwater specimens in the Chicago area and, indeed, one of the largest in the nation.

The sheer diversity of our offerings leads to stunning displays, and our specially trained staff is well-equipped to help collectors make confident choices from the dizzying array of choices.

To ensure you with the best selection, we receive new shipments up to 10 times per week – almost unheard of in the aquarium industry! Our specimens come from the farthest reaches of the ocean, including Bali, Australia, the Red Sea, Brazil, Hawaii, the Solomon Islands, Japan, Jakarta, New Guinea, and interesting waters off of the U.S., such as Florida and Hawaii.

In line with responsible collecting, we also offer cultured and farm-raised animals for collection.

For the sophisticated, experienced, or adventurous collector, we also offer special, “hand selected,” one-of-a-kind specimens like the Weedy Scorpionfish (Rhinopias sp.), Conspicillatus angel, and scientifically undescribed fish.

Order Knowledgeably and Collect with Confidence

Our goal is to help you create your dream collection. We will help you pick the right specimens to meet your goals. Then, we guarantee all of our animals, we give you all the information you need to keep them healthy and strong, and we carry all of the supplies you’ll ever need to maintain their perfect environment so you can enjoy them worry-free.
