A refugium is an external tank, usually smaller, that is used to house smaller fish and invertebrates for cultivation and/or feeding the fish in the display tank. It can be connected to the main tank and is sometimes apart of or separate from the sump. You can even get a hang on the back of the tank type refugiums or DIY a power filter to use as a refugium. See the DIY for more information. A refugium provides isolation for those more delicate specimens that can easily and quickly become food for the larger fish in the display tank.
