WWC Yellow Submarine Zoanthids is a hardy fast growing strain of zoas that we have been growing here at WWC for many years. Their appearance features an olive green skirt with a bright yellow ring on the oral disk and a blue circular pattern around the mouth. They are a medium sized polyp and will adjust well to a variety of aquarium conditions. Given favorable lighting, flow, and nutrient levels in the tank you should expect growth of several new polyps every few weeks. The Yellow Submarine Zoanthids is a good choice if you are looking for a zoa that will cover a rock, or fill in a zoa garden quickly.
