This personal jelly fish tank is filled with 3 LED-lit jelly-like fish shapes that float calmly and somewhat creepily around their own little fish tank. They’re not real jellyfish, so they don't require feeding (although, if Jellyfish don't like Hot Pockets, they would starve in my house anyway). Of course, this came from Japan where jellyfish are eaten and battled regularly. The product page touts it as perfect for “anywhere people like to relax,” but I find poisonous stingers somewhat unrelaxing. Maybe this is better for a haunted house.
