Are there any predators to Berghia nudibranchs?
Please keep in mind there are times when creatures considered “reef safe” do not act as expected. But, generally speaking, the creatures below are those you should be most concerned about when adding Berghia. Any fish that aggressively hunts the rock at night for food other than algae, including some wrasses, butterflyfish and some dottybacks. It’s hard to predict fish behavior. As a general rule if your fish spends a lot of time “hunting” your reef on a regular basis, especially at night, it is suspect for hunting berghia. Shrimp that scavenge at night: Peppermint shrimp are the worst, also coral banded shrimp and possibly camel shrimp (does not include cleaner or fire shrimp). Aggressive crabs that scavenge for food: Sally lightfoot crabs, arrow crabs, pom pom crabs, rock crab hitchhikers and emerald crabs that have no algae to eat (does not include emerald crabs with algae available to eat or any hermit crabs). Also, aiptasia may eat a Berghia if it is accidentally dropped directly
