The Berghia Nudibranch eats only one thing in a saltwater aquarium: the invasive Aiptasia anemone. Since they eat only Aiptasia Anemones, Berghia Nudibranchs are guaranteed 100% reef safe and will never harm anything in your aquarium! You can learn more about the Berghia Nudibranch from our Berghia Q&A or Berghia Information page. If you're not sure what an Aiptasia Anemone looks like or have heard of other methods of Aiptasia anemone control, you can find out more under the Aiptasia Information page.
