Frequently Asked Questions

When will my item be delivered?

Orders are dispatched using the courier UPS. They are sent by next day delivery. Delivery will be made by either 12:00, 14:00 or 18:00, this depends on your address. If you would like confirmation of which time it will be please send us an email on info@berghiaonline.com

You can select your delivery date on the checkout page, delivery is available on Tuesdays and Thursdays

Orders must be placed a minimum of 24 hours before your chosen delivery date to give us sufficient time to properly pack your Berghia

How many Berghia do I need?

From our experience we recommend a minimum of 1 Berghia per 50 liters of water, with a minimum of 3.

The more you have the quicker they will eat and more likely they are to find each other in your tank to mate. 

The more they mate the more egg strands they lay meaning the more Berghia you get and the cycle continues.

How do I acclimatise the Berghia?

You should acclimatise the Berghia over a 30-60 minute period as you would do to any other live animal you place into your tank. 

How does your arrive alive guarantee work?

It is normal for Berghia to arrive looking sluggish due to the transport process and them being nocturnal, after they have warmed up they will soon be hunting for aiptasia again. 

Our postage and packaging is tried and tested and it is very rare for any problems to occur.

If in the unfortunate event that your Berghia do arrive deceased, please take a picture and notify us on the day of arrival, we will then be able to arrange  a replacement to be sent out. Postage cost is included in the arrive alive guarantee.

You must accept delivery on the scheduled day, if the delivery is delayed through events not in your control (such as a delay with the courier) then we will retain responsibility for the alive arrive guarantee. If however the delivery is not made at the fault of yourself (such as not answering the door, providing an incorrect address etc) then the arrive alive guarantee will not be valid. 

How big are the Berghia that you sell?

We only sell the highest quality Berghia once they have matured and developed correctly.

This is because we want to make sure every Berghia you receive is going to do its job well.

You can expect to receive Berghia that are at least 8mm in length and are starting to lay eggs.

Will anything in my tank harm the Berghia Nudibranch / Do they have any predators?

We have included a list below of inhabitants that may harm your Berghia Nudibranch, along with our recommendation on how the risk should be managed

Wrasses (except Fairy wrasses) and Long nosed hawkfish – Depending on their temperament they have been known to try to eat Berghia. However on almost all occasions they will spit the Berghia out once the Berghia releases the stinging cells it retains from eating Aiptasia. This will not hurt the fish but will be unpleasant and they are highly unlikely to ever try tasting another Berghia. WHilst there is a chance the spat out Berghia will survive it may sustain fatal injuries from the encounter.

Our recommendation: Purchase one extra Berghia Nudibranch to counter the chance of one being killed.

Peppermint shrimp – Again this depends on their temperament, however these pose the biggest risk to Berghia out of any other inhabitant. Peppermint shrimp are known to enjoy hunting Berghia Nudibranch, especially at night which is whne the Berghia come out. This is an issue for many people who buy Berghia as they have often already bought these shrimp to try to tackle the Aiptasia problem.

Our recommendation:  We reccomend you play it safe and remove the peppermint shrimp. Peppermint shrimps are easy to remove using a trap constructed from a plastic bottle. Simply cut the top of the bottle and put it back in backwards to create a entrance that becomes more narrow as they go into the trap. Check on it regularly.

Camel Shrimp, Coral banded shrimp and aggressive crabs that have no food to eat – We consider these to be a low risk to Berghia Nudibranch, it is rare for them to be aggressive and if so it likely causes limited harm.

Our recommendation: Ensure your shrimp and crabs have food available.

Bristle Worms – Bristle worms will not seek out Berghia Nudibranch to attack, they may however attack them in defense of their nest to protect their eggs.

Our recommendation: Be careful when putting your Berghia into the tank, try to place them on higher rock. If you have a particularly bad bristle worm infestation consider buying a bristle worm trap, or buying a couple extra Berghia.
