Small Saltwater Aquariums — Nano Aquariums
Picotope, nano, or mini aquarium, these are all terms used to describe the smallest of the small aquariums set up for a freshwater or saltwater reef. These small fish tanks can be very challenging, as the smaller an aquarium is, the more difficult it is to maintain. Beginners should start out with at least 29 gallons of water for their first small reef, but these smaller units are great for freshwater or experienced fish keepers who want a new challenge in a small space. Whether your preference is the Red Sea Max or the Nano Cube, these mini aquariums are a lot of fun and can be very rewarding.
