Easier to set up and maintain than traditional at-home saltwater tanks, this is the 13 1/2-gallon saltwater aquarium designed by a marine biologist and microbiologist. It provides you with step-by-step instructions and specific supplies to assemble a perfectly balanced saltwater ecosystem without requiring extensive time, research, and guesswork. The glass tank arrives with an integrated pump, filter, thermometer, hydrometer, heater, LED lamp, sea salt packets, sand, and instructions. Once set up and registered, the living organisms are then delivered including a live rock, two clownfish, a Rainford’s goby, and four soft corals. The fish, coral, and the live rock are all sustainably raised in captivity on aquaculture farms to ensure health and eliminate any impact on ocean life. AC plug. Tank 22" L x 11 1/2" W x 15" H.
