Reiman Aquarium

Take a journey from the Great Lakes to the Caribbean when you step into the Reiman Aquarium.

Begin in the fresh waters of Lake Michigan, moving past the Great Lakes and into the St. Lawrence Seaway, where fresh water meets the salt water of the Atlantic Ocean. Finish your journey by going southward to the Florida Keys and finally to the Caribbean Sea. When was the last time you reached out and touched a shark? Take your journey even further by actually touching fish in our Touch Tank area and studying sea life in our Underwater Labs.

The Reiman Aquarium also includes an aquarium exhibit featuring weird, wild, and colorful freshwater species from around the world. Sponsored by PPG, these tanks feature stunning frogs, a terrifyingly wonderful alligator snapping turtle, and brilliant and beautiful freshwater fish from Asia, Africa, and South America. Explore the colors of nature and the nature of color in Weird & Wild: Colorful Freshwater Species from Around the World.


  • Lake Michigan Tank: The largest of our tanks holds 75,000 gallons of water and is home to many species including Lake Sturgeon, Paddlefish, Bigmouth Buffalo, Largemouth Bass, Smallmouth Bass, Shortnose Gar, Bowfin, Shovelnose Sturgeon, and more!
  • The Great Lakes Composite Tank: Home to species like Yellow Perch, Smallmouth Bass, and Bluegill.
  • St. Lawrence Brackish Tank: Brackish water is usually found where rivers meet the ocean. The force of a river drives freshwater far out to sea, while the influence of tides pushes ocean water a long way up river. It includes species like Cave Transparent Goby, Gulf Todfish, and Saddled Blenny.
  • Northeast Atlantic Tank: This tank holds 8,000 gallons of water and contains a variety of fish that are commonly found within this part of the ocean such as Striped Bass, Snowy Grouper, and Summer Flounder.
  • Jellyfish Tank: This “lunar experience” is home to our Moon Jellyfish and a favorite for visitors of all ages.
  • Florida Keys Tank: The 6,000-gallon tank resembles a colony of Mangrove roots that are home to many Southern aquatic species. Featured species include Rock Beauty, Gray Angelfish, Cottonwick Grunt, High Hat, and Blue Striped Grunt.
  • Seahorse Tank: The tank showcases varieties of Seahorses, Banded Coral Shrimp, and Horseshoe Crab.
  • Caribbean Tank: The centerpiece of the Reiman Aquarium, this area features a walkthrough tunnel running through 65,000 gallons of salt water. The tank is home to species like Permit, Blue Parrotfish, Blue Stripe Grunt, Yellowtail Snapper, Atlantic Spadefish, Porkfish, French Grunt, Lookdown, Smallmouth Grunt, Blue Runner, and Rainbow Parrotfish. Weekend Public Interaction Dives in the Caribbean Tunnel are most Saturdays and Sundays at 2pm(Dives subject to staff and volunteer availability).
  • The Touch Tanks: The larger touch tank has two sides. The colder freshwater side (around 60 degrees) is home to Lake Sturgeon, while the salt water side (closer to 80 degrees) contains Cortez Round Stingrays and White Spotted Bamboo Sharks. The Stingrays barbs have all been trimmed and Bamboo sharks pose no threat to humans. A smaller, additional touch tank perfect for little ones and those who require wheelchair accessibility, was added in October 2015.
  • The Underwater Labs: This exhibit features a “submarine” split up into 3 pods and staged as an underwater laboratory where you can explore and study like real scientists.
    • Human Underwater Lab– Learn about diving and the gear required to support human life underwater. The pod features a working Periscope from a naval vessel that provides a live view of the world above.
    • Ichthyology Lab– Gain knowledge of fish biology, as well as some strange defenses some fish have against predators.
    • Water Quality Lab– Discover more about the life sustaining importance of water quality worldwide.
