Berghia Nudibranch (Aiptasia Eating)

The best natural defense against Aiptasia is Berghia (Berghia Nudibranchs), as their sole diet is Aiptasia anemones. Berghia are non-toxic to corals and fish and are considered to be completely reef safe.

We recommend at least 1 Berghia per 10 gallons, but NEVER less than 3 Medium Berghia. Berghia need each other to Hunt, Feed & Breed. If you're not sure, it's best to overestimate rather than underestimate.

Acclimation Instructions

Begin making partial water changes to the Berghia container by pouring off a little water and adding tank water, repeat, until you feel the water temp and parameters are the same (about 30 minutes to an hour). Packing water is new, clean natural seawater with no chemicals added. It is good to pour the water off into a bowl in case you happen to pour a Berghia out. When you feel they are fully acclimated to your water quality parameters, the preferred method of introducing Berghia is to place the container on it’s side on a rock (not in the sand) near, but not on top of, a bunch of Aiptasia, as Aiptasia can eat Berghia as well. Wedge or weigh it down and allow the Berghia to crawl out on their own accord. If you purchased many Berghia, you can wait till about half crawl out then move the container to another location for the remainder. Remember, they are colonial and are best introduced as a colony. We do not recommend using the pipette to add your Berghia to the tank, however if you do,, TURN OFF ALL WATER FLOW, pumps and powerheads alike and be very careful as they are VERY FRAGILE.. Don’t feed fish during acclimation time. Sit back and wait with patience and allow Nature to do it’s job.

IF YOU HAVE WRASSES Feed fish well….Turn off lights,… Allow fish and predators to settle down. You can add them at night, once the wrasses are under the sand, but make sure you keep the lid off the container until then. The important thing is to allow them to seek refuge into the rocks without the wrasses getting curious enough to try them out. KEEP THEM AWAY. Once the Berghia have found their way deep into the rocks they have opposite Sleep/Wake cycles and should not pose a huge problem to having success.
