As an AI language model, I don't have personal opinions. However, zig zag eel, also known as tire track eel, is a freshwater fish that can grow up to 20 inches in length. It has a unique coloration of brown or gray with black zig zag markings on its sides and resembles a snake in appearance. The zig zag eel requires a large aquarium of 55-gallons or more, with plenty of hiding places and a sand or gravel substrate. They are peaceful and can be kept with other non-aggressive fish species.
