This small sea slug is truly an aiptasia eating superhero. It will seek out and consume all the aiptasia it can find in a home aquarium, hence its other common name, Aiptasia Nudibranch.
The Berghia Nudibranch is generally whitish in colour and is sometimes semi-translucent. Generally this invertebrate is known more for its function than for its beauty.
The Berghia Nudibranch has a wide range and can be found in both the temperate and tropical waters of the Caribbean, the Atlantic and the Mediterranean. Since this nudibranch eats only aiptasia anemones it is found in the same habitats as its food source. This means that in a home aquarium they will require
ample live rock since that is where aiptasia are generally found. They are primarily a nocturnal predator but can sometimes be seen hunting during the day.
Berghia Nudibranchs are generally only kept in home aquariums for one reason, to control aiptasia, a function they perform admirably. These small anemones can be dangerous to corals, fish and other invertebrates so removing and controlling them is very important. It is generally recommended to keep 1 nudibranch for every 10 gallons to control a moderate aiptasia problem. It is recommended that when a Berghia Nudibranch is first introduced into a tank they are placed near an aiptasia anemone so that they can quickly find their first meal. Since their diet consists solely of aiptasia they will starve if their food source runs out. The Berghia Nudibranch appears to be immune to the stinging tentacles of aiptasia and will consume them voraciously. This small sea slug can make it much easier to deal with an aiptasia infestation with the added benefit of having a negligible impact on the tank’s bioload.
