Aquarium/fish tank (Worthing BN13)

Described as “desktop” when I bought it. About 20 litres. (Lid home made as it didn’t come supplied) I used it for a Betta fish (Siamese fighting fish) who lived happily for 4 years in it. Filter has a new cartridge. White sand is new and washed. Two plastic plants and small decorative thing included. Plus a usb LED light. (Please note: there is no heater as I broke it while cleaning, although it very rarely came on as my home is kept warm)
