Berghia Nudibranch for Targeted Aiptasia Control in Saltwater Reef Aquariums, Available in Regular and XL Sizes

Berghia nudibranchs offer reef keepers a focused, biological way to manage unwanted Aiptasia in saltwater aquariums.

These peaceful marine slugs eat only Aiptasia, allowing them to target pest anemones without harming corals, fish, or other invertebrates.

Regular and XL sizes support different aquarium plans. Berghia fare best in groups where they have steady access to Aiptasia, sheltered rockwork, and low to moderate flow.

Key Features

• Their Aiptasia-only diet concentrates feeding on the unwanted anemones, providing targeted biological control without a chemical treatment.
• A reef-safe, peaceful temperament allows them to forage without damaging corals or other tank inhabitants.
• Nocturnal feeding suits an after-dark introduction, when these delicate slugs can settle into sheltered rockwork with less exposure.
• Aquacultured specimens are acclimated to home aquariums and actively feeding before shipping, supporting a smoother transition into suitable reef conditions.
• Groups feed and reproduce cooperatively, increasing their effectiveness when tackling established Aiptasia infestations.
• XL Berghia can consume 2–5 Aiptasia per day, giving keepers a higher-capacity size option for affected aquariums.

Introduce Berghia at night in a low-flow area away from wrasses, dottybacks, pufferfish, triggers, carnivorous shrimp, and filefish. Maintain stable reef parameters and enough Aiptasia for feeding. Once the Aiptasia is gone, relocate the nudibranchs to another affected aquarium so they do not starve.
