A breeding Berghia nudibranch lays eggs once every few days (1-3 or 1-4). It is generally recommended to start with the 1/2 inch size, to ensure the best chance of establishing a breeding population in your tank. Breedingīerghia Nudibranchs will mate and lay eggs once they reach maturity. Yes, a few popular aquarium crabs will eat Berghia nudibranchs, including Arrow crabs, Emerald crabs and Sally Lightfoot crabs. I guess it’s an eat aiptasia or be eaten world in the ocean. It is a bit ironic to me, but if you have any other aiptasia-predators in the tank, they will also very likely be nudibranch hunters as well. Especially because you wouldn’t need to add both if the much more readily available peppermint shrimp just did their job in the first place.Ĭoral banded shrimp may also be problematic.
Peppermint shrimp, added to tanks because of their taste for aiptasia flesh, also eat Berghia nudibranchs, which seems ironic to me. Yes, certain popular aquarium shrimp species will eat Berghia nudibranchs. If you have a Melanurus wrasse, six-line wrasse, Aiptasia-eating filefish, or a long-nose hawkfish, you may want to think twice about adding them to your tank, since the Berghia will be a nice little appetizer for them. The majority of saltwater aquarium fish will not eat Berghia nudibranchs, but there are several species that will. In fact, they won’t even eat Majano anemones (a close cousin of the aiptasia). If you don’t order enough, they could starve or get eaten (by shrimp, crabs, wrasses, etc.) before they reach a population size suitable to complete the task.īerghia nudibranchs will not harm corals or other invertebrates. The original population is likely insufficient to eradicate the anemone pests, but it is when you have established future generations of the sea slug that you will reach a level where elimination can be obtained. The rationale for this is that if you hope to eliminate aiptasia from your tank, the invertebrates will need to find each other to gang up on each individual anemone (that’s how they hunt and take down an anemone) and they will need to find each other to mate and reproduce. The two sites specializing in selling Berghia nudibranchs recommend no less than 6 per tank (in any size tank) and otherwise approximately 1 for every 10-12 gallons of aquarium volume. So the more you start off with, the faster your population will grow. That means you need to have lots of eggs and sea slug babies. They need each other to take down a full-sized anemone, and while they are hermaphroditic, they do require another slug to successfully mate.Īlso, depending on the severity of your aiptasia issue, you’re probably going to need an entire ‘population’ of slugs to address the problem. After about a month in the tank feasting on aiptasia, one individual was pushing about an inch in total length How many Berghia nudibranchs per tank?īerghia nudibranchs need each other–for hunting and for reproduction. Their size will also swell a bit after a good meal. When I purchased several medium-sized adults, I found that there was quite a distribution in sizes.
#WHICH PEPPERMINT SHRIMP EAT AIPTASIA FULL#
They are sexually mature (and therefore able to reproduce) at about 1/2-inch in length and grow to a full adult size of about 1 1/2-inches in total length. They are sold by aquaculture facilities/breeders anywhere from 1/4-inch in length to about 3/4-inches in length. They do best with high-quality reef tank water parameters How big are they?.
