Have your own virtually maintenance free aquarium complete with a pair of jellyfish. The jellyfish bob around with their realistic tendrils floating behind them as they dance in the atmospheric colour changing lights. Just fill the lamp with 700ml of water, (distilled water will last longer), the top cap simply removes and there is a little rubber bung in the hole. Add batteries, and you\'re good to go, the colour changing lights will gently morph between colours creating a relaxing and mesmering jellyfish show.
