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 Rainbow Trout, Lake Sturgeon, Buffalo Fish, Largemouth Bass, Smallmouth Bass, Black Crappie, Bluegill, Long Nose Gar, Bowfin, Paddlefish, White Bass, Walleye, Common Carp, Shovelnose Sturgeon, and Freshwater Drum.
- The Great Lakes Composite Tank: Home to species like Yellow Perch, Smallmouth Bass, and Blue Gill.
- 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 Killifish, Pin Fish, and Blue Crab.
- Invasive Carp Tank: This area focuses on the growing challenge posed by invasive species and illustrates the pathway that invasive species travel to get to the Great Lakes. Thankfully, this is one of the only places in Wisconsin – for now – where you will come in contact with Asian Carp such as Bighead and Silver Carp.
- 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 Black Sea Bass, Flounder, Striped Bass, and Scup.
- Jellyfish Tank: This “lunar experience” is home to our Moon Jellies 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 Angelfish, Gray Angelfish, White Grunt, High Hat, and Blue Striped Grunt.
- Caribbean Invasive Tank: Home to various fish, Black Edge Moray Eel, and the dangerous Lion Fish. It is native to the Pacific Ocean, but has become a destructive predator in the Atlantic and Caribbean.
- Seahorse Tank: The tank showcases varieties of Seahorses, Arrow Crab, Cleaner 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 the Porcupine Puffer Fish, Permit, Black Durgon, Squirrel Fish, Blue Striped Grunt, Yellowtail Snapper, Atlantic Spadefish, Pork Fish, French Grunt, Blue Tang, Lookdown, French Angelfish, Hogfish, Smallmouth Grunt, Blue Runner, and White Grunt. 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 Sting Rays, Bamboo Sharks, Starfish and at times Sea Stars and Pencil Urchins. The Stingrays barbs have all been trimmed and Bamboo sharks pose no threat to humans. A smaller, additional touch tank 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 some strange defenses some fish have against predators.
- Water Quality Lab – Discover more about the life sustaining importance of water quality worldwide.
