You can keep a clean empty fish tank in your storage unit and it can be included in your self-storage insurance with Store and Insure. Some aquarists like to keep a spare tank in external storage. Most storage companies will not allow you to keep a working aquarium in a storage unit and you cannot insure it with us. But you can insure clean dry aquarium equipment, including tanks, pumps, filters, heating, lighting and decorations, with Store and Insure.
