Jellyfish Party #2 by photosynthesis Photography Abstract
Dirty water. That seems obvious for just about all marine organisms but it certainly holds true for pelagic or free-swimming jellyfish. Moon jellyfish need water that is free of organics and degrading nitrogen compounds. The main culprit in jellyfish dying in aquaria is thought to be elevated levels of ammonia. Additionally, jellyfish can do poorly with other stinging animals like various hydroids. Some public aquariums use a routine system of completely draining and disinfecting their jellyfish systems regularly. This practice is typically not followed by commercial systems or by home hobbyists.
There are jellyfish that don't sting. They actually lost their ability to sting. In a lake called the Jellyfish Lake, people can actually swim among thousands of these pulsing, gelatinous creatures. Located in the Pacific Republic of Palau, the body of water is a landlocked saltwater lake which trapped the jellyfish a million years ago when a submerged reef rose from the sea and blocked them going out.10 "Over the centuries, with no predators or need to capture food, they gradually lost their long tentacles and their ability to sting" . These jellyfish have come to rely on the sun for food. Meaning they rely on the symbiotic algae the live within their tissues for food. These jellyfish use their light-sensing organs to swim towards the sun to ensure that the algae receives enough sunlight for photosynthesis. The algae releases nutrients which the jellyfish absorb (a href="#3">(3). It has been observed that if these algae die, then the jellyfish will continue to consume its own tissues which may even lead to its death Jellyfish lake gets thousands of visitors each year to swim among these graceful creatures.

Moon jellyfish can make wonderful aquarium inhabitants. Several hobbyists have had success in not only keeping jellyfish but breeding them and completing their life cycle. These animals are not only successfully kept in home aquaria, but they are collected at incredibly low numbers from the wild with no effect on wild populations. Keeping jellyfish is a fantastic source for gaining knowledge and furthering our understanding of them, and advancing jellyfish husbandry in foods, filtration, system design, grow out and more. In general jellyfish love to eat Artemia nauplii. Which is to say that that they love to eat newly hatched baby brine shrimp. In addition to this, copepods, shrimp, chopped seafood, and zooplankton are also important food sources for jellyfish. Fortunately, there are people harvesting and raising foods for jellyfish on a daily basis, and those foods are available for purchase. The frozen foods are highly nutritious and very convenient to use. But culturing techniques and experiments with other commonly available prepared foods is still on the horizon.
Moon jellyfish need a few basic items. They require gentle water flow to keep them suspended and to allow their tentacles (equipped with the familiar nematocysts) to capture food. This is usually accomplished by creating a kreisel or pseudokreisel aquarium. The term kreisel comes from a German term meaning spinning or rotating. These aquariums feature circular flow that keep the jellyfish slowly moving around without hitting pumps, screens, aquarium sides, etc. The jellyfish needs the space in the water to properly expand, and it needs the flow to gently bring food items to it. The type of food consumed by jellyfish is currently being explored, but some commercial foods are available. Visit to see the process of making your own food, or to purchase theirs. In general, jellyfish eat small copepods and protein-rich organisms swimming in the water column such as juvenile shrimp (krill), brine shrimp, and a plethora of pelagic copepods. The jellyfish most commonly kept in aquaria are fed a mixture of brine shrimp, copepods, phytoplankton (to feed the zooplankton) and finely chopped seafood. Private companies have developed and are continuing to develop and produce their own blend of foods for jellyfish, but experimenting with other readily available foods may lead to great success for adventurous hobbyists. With the ever growing availability if prepared foods for the aquarium market there are always new foods that may be well suited for jellyfish. Take note- not all jellyfish eat foods that can be so easily prepared. Some jellyfish even live by eating other jellyfish. For this reason it is important to know what your jellyfish naturally prey upon before selecting them for your aquarium. The Aurelia moon jellyfish are a good choice since their nutritional needs can easily be met.

Shown here an aquarium with a gentle current is being used to grow moon jellyfish polyps. These polyps are settle onto acrylic plates where they grow and divide.
Another jellyfish species that is sometimes kept in marine aquariums is the Moon Jellyfish (Aurelia aurita). It can reach a maximal size of 30 centimetres / 12 inches, and a large aquarium is therefore necessary. If you touch your Moon Jellyfish it can sting you, but the sting is not dangerous as long as you are not allergic or extra sensitive. Just like the Upside Down Jellyfish, Moon Jellyfish feed on micro plankton, but the Moon Jellyfish will also eat larvae in the wild and aquarists that keep Moon Jellyfish will therefore usually feed their pet large amounts of live brine shrimp. Moon Jellyfish is commonly found in temperate waters and you should keep the water temperature between 12 and 18 degrees Celsius / 55 to 65 degrees Fahrenheit in your aquarium. In many cases this means that you will be required to install a refrigeration unit. If you have a cool room, such as a basement, it can however be possible to successfully house Moon Jellyfish without any refrigeration unit

One of the most commonly kept Jellyfish species is the Upside Down Jelly fish (Cassiopea andromeda). This jellyfish species originated from Philippine water, but can today also be found around Hawaii. It is believed to have been involuntary introduced to the Hawaiian fauna by ships around World War II. If you want to keep an Upside Down Jelly fish you must create an aquarium with an upwards water flow than can lift the jellyfish from the bottom. When you choose aquarium you should bare in mind that a fully grown Upside Down Jelly fish can reach a size of up to 20 centimetres / 8 inches in diameter. Upside Down Jelly fish eats micro plankton. The Upside Down Jelly swims upside down since this jellyfish depend on specific algae that it forms a symbiotic relationship with. By swimming with the algae on top, the jellyfish makes it possible for the algae to absorb sunlight and carry out photosynthesis.

Moon jellyfish is a funny term. It is used by some people to describe pelagic jellyfish, but most use it for the particular a group of jellyfish from the genus. There may be close to 20 species in , and to be honest I can't tell them apart. These jellyfish usually have very large translucent bells (even up to 15 inches across!), small, short tentacles, four gonads and slow, rhythmic pulsing. The most readily available moon jellyfish species for is The moon jellyfish are found worldwide. They live in tropical warm waters, cooler temperate waters, and even into cold water systems. They drift along in ocean currents and are not contained to reef settings. For this reason they can drift hundreds if not thousands of miles and their offspring are far reaching.
Two species of the moon jellyfish are available to hobbyists. is a species of moon jellyfish naturally living in the temperate waters off of California. Given the great number of hobbyists and public aquariums in California these animals are sometimes found in the hobby and on display. They are not readily available for purchase, but are readily available for collection by the more outgoing aquarists. If you'd like to keep Aurelia labiate my advice is to keep a chilled aquarium of roughly 50 degrees, and to contact a public aquarium in California as a potential source of jellyfish. Some of them have literally thousands of small medusa jellyfish on hand at all times.

The other species of moon jellyfish we see are the . These jellyfish are found in warmer waters and I've personally seen many of them on reefs with temperatures around 80 degrees. For this reason, I much prefer them. They are typically an easier to keep jellyfish, if there is such a thing, and may not require a chiller in the system. Ideally I'd recommend keeping them in aquariums around 79 degrees. These jellyfish are always available for purchase from places such as .
