Saltwater, freshwater, coral, and expert guidance for every aquarist in Oshkosh, Wisconsin.
Sanctuary Aquatics on Jackson Street is the kind of shop that turns a casual errand into a two-hour conversation. Built on real engineering know-how and deep hobbyist experience, the store carries saltwater and freshwater fish, coral, invertebrates, aquatic plants, and the equipment to keep all of it thriving. Whether someone is setting up their very first five-gallon tank or chasing a rare specimen for a reef system they've been refining for years, the staff here meets them exactly where they are.
The 4.6-star rating across more than 200 reviews doesn't happen by accident. Customers drive in from across Wisconsin specifically to visit, and many call it a destination stop on day trips around the state. The team is known for going deep on care guidance, not just ringing up a sale. Bring a question about a species you've never kept before and expect a real, thorough answer.
