Collection: 500 Litre Fish Tanks

Space-defining tanks, which are designed to give experienced fishkeepers the freedom and space required to build a beautiful, dynamic underwater ecosystem, our collection of extra large aquariums feature tanks that support 500 litre capacities. In order to hold such large volumes of water safely, to protect both your home and the tank inhabitants, plants and corals housed within, these 500L tanks are specially built by trusted brands, including D-D and Red Sea, using high-quality materials. Our collection also includes extra large tank-only aquariums, as well as those with purpose-built cabinets which strategically house the supporting equipment and any supplies you have for maintenance, allowing you to keep everything you need in one convenient place.
