Introducing the Superheroes of the Aquarium: Berghia Nudibranchs!

Meet the newest superheroes of your aquarium: Berghia nudibranchs! These tiny creatures are a type of sea slug, and they’re here to help you rid your tank of pesky pests. Not only do they look like something out of a sci-fi movie, but they will also help keep your tank clean and healthy. Read on to learn more about these incredible critters and why you need them in your aquarium!

What Are Berghia Nudibranchs?

Berghia nudibranchs are quickly becoming one of the most recognizable types of sea slugs in the reef hobby. They have an awesome alien-like appearance, with slender bodies, long antennae-like appendages, and bright white color. Despite their small size (they usually measure less than 1.5 inch long), these critters have an important job: they feast on Aiptasia anemones, otherwise known as glass anemones or rock anemones. Aiptasia can be quite destructive to delicate corals in reef tanks if left unchecked, so having Berghia nudibranchs around is essential if you want to keep your marine environment healthy.

Why Do I Need Them?


Berghia nudibranchs are invaluable for keeping Aiptasia populations under control—no matter how big or small your aquarium might be. In fact, some experts suggest adding two Berghias for every 10 gallons of water in larger tanks. Not only will these critters eat any Aiptasia they come across, but they’ll also reproduce quickly enough to keep up with any new Aiptasia growth you may encounter. Once all the pesky pests are gone you can remove the Berghias and pass them onto a friend suffering from the same issue—making them a practical and efficient addition to any reef tank!


Berghia Nudibranchs make amazing superhero additions to any aquarium hobbyist's home! Not only do they look fascinatingly alien-like, but their strong appetite for Aiptasia makes them invaluable for keeping pesky pests under control. So if you’ve got a problem with glass anemones in your tank and need some help getting rid of them, don’t hesitate to add some Berghias into the mix—your corals will thank you later!
