Milwaukee Aquarium Society (MAS) hosts several swap meets each year to help connect the Milwaukee aquatic community with sellers of fish, plants and aquarium supplies. It’s a great opportunity to find unusual species and speak with the sellers, who are typically the breeders who raised the fish. Customers have the opportunity to buy from local and regional vendors, and find some great bargains!
