Frequently Asked Questions

The number depends on the size of your tank and the severity of your Aiptasia infestation. Generally, we recommend 3–8 Berghia for smaller aquariums (10–100 gallons) and larger groups for bigger tanks.

Yes. They are reef safe and will not harm corals, fish, or other invertebrates.

Berghia feed only on Aiptasia, once the food source is eliminated, their population will naturally decline. Berghia will also graze as snails, cleaning up the Aiptasia bio-film and go dormant. Some aquarists choose to pass them along to other hobbyists in need.

Yes! We provide multiple articles and care guides to help you introduce and maintain Berghia successfully in your aquarium.

Yes, live arrival is always guaranteed. Our team has tried and proven safe packaging and shipping practices.

UPS and FedEx can experience weather and technical delays. Tuesday or Wednesday allows 2 days for recovery time before a weekend delay.  Live shipments will arrive this same week, preventing carriers from A 3 day technical issue delay over the weekend.

Pipettes can knock some Cerata off smaller Berghia and all the Cerata off a larger Berghia. Cerata are used for digesting Aiptasia and for Berghia Defense in a technique called Bristling. Berghia can move into the reef naturally, safely, without help. Slow the circulation pumps down. Brace the shipping jar against a reef rock with shells or another rock. Allow the Berghia to exit the shipping jar by themselves.

Berghia nudibranchs prevent damage to Live Corals and Fish from Aiptasia Exposure.

Obtain a reef rock and or possibly a couple of shells to hold the Berghia shipping jar down on or against the rocks. Complete a dry or practice run before the Berghia arrive. If drip acclimation is your plan, obtain and test drip lines ahead of time. Select a suitable bucket for the overflow just in case. IF there is a flaw in your setup, there will be time to obtain supply replacements before the Berghia arrive. Look over our acclimation demo photos placing shells to hold the jars and read the acclimation articles beforehand. There is a handout available for download to explain a few things to expect.  Planning will assure a smooth transition. Waiting until night and lights off is not necessary, as long as the lights are turned down. Berghia will naturally crawl out of the jar into the rocks in a few hours or less as they prefer to be in the rocks. To start the process, turn sump lights off, remove the jar parafilm seal, and float the jar for 15 minutes in your sump. This will equilibrate the shipping jar temperature with your reef. Proceed with the completion of your plan.
