As regards the breeding of these animals, the first step to take is to find the specimens to be included in the special aquarium. For the availability of these animals it is good to inquire about the structures that have specimens that can be supplied to those who request them.
The choice of the jellyfish species falls on Aurelia aurita (Moon Jellies), a homegrown species as well as proven adaptability and good resistance to life in captivity.
Once the animals have been found, it is good practice to carry out a “drop by drop” acclimatization long enough for 60 minutes and then gradually insert each individual animal as they are particularly subject to the formation of dangerous air bubbles if in contact with air, a similar situation that occurs in the insertion of other animals, often for example hedgehogs or hermit crabs.
With regard to the feeding and maintenance of the tank, there are two other very important aspects that always relate to the structure of the tank for these animals. Feeding jellyfish is quite challenging but not impossible and can be safely done using a 5ml syringe without needle filled with brine shrimp or rotifers nauplii in the case of very small animals. It is good practice that the nauplii are free from cysts, in order to avoid serious damage to the animal.
In addition, the animals must be fed a little and several times throughout the day. From the maintenance point of view it is good to highlight how the jellyfish tank must be perfectly clean and free from food residues or other; surely for this purpose it can be useful to use a plastic tube operated by a low voltage pump, taking care not to suck the jellyfish carelessly and these operations must be performed daily.
Clean the tank in such a way as to break down pollutants that are potentially harmful to these animals, most importantly, all ammonias.
These animals have been regularly bred by private individuals for several years now and unfortunately very little is known about the breeding of these animals, so much so that the importers do not have any in their price list except for a few individuals for public aquariums.
One piece of advice I would like to give to those who want to try their hand at breeding these animals is to buy a good book (“How to Keep Jellyfish” by C. Widmer is an excellent book) and read up as much as possible.
The breeding of these animals is challenging but not impossible. The first step is to precisely document as much as possible, and have several years of success and failures behind you so as to have accumulated enough experience to be able to succeed in this fascinating adventure.
