Yes. You heard it right, We can pet jelly fish at home.Water flow is key. Jellies are like a wet ball of tissue floating around in the tank. If they get close to a filtration intake in a regular fish tank, they would get sucked in and badly mangled. They’re made up of over 90% water so they’re very delicate. The water flow in the tank has to be designed to have a very gentle outflow spread out over a large surface area.

Type of Jelly Fish

MOON JELLYFISH: Moon jellies are very common, and odds are if you have visited an aquarium and seen a jellyfish, you saw a moon jelly. They do sting, but the irritation is usually rather mild, and they are not considered dangerous by scientists.

BOX JELLYFISH: The box jellyfish’s venom is among the most deadly in the world, containing toxins that attack the heart, nervous system, and skin cells. 

LION’S MANE JELLYFISH: Lion’s mane stings, though not generally considered fatal, can cause a lot of pain. “Stings from large lion’s mane can be particularly dangerous, as the thousands of thin tentacles can each extend to several meters long.

Feeding care

You should feed your jellies twice a day, once in the morning and once at night. Live shrimp brine will keep in the refrigerator for up to two weeks. You can feed the jellyfish through a small opening in the tank to prevent getting stung by their tentacles. The jellyfish should catch and ingest the food on their own.

Why pet moon jellyfish ?

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 habitat needs

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. 

ellyfish also need very clean water and stable water chemistry. This is usually accomplished by standard aquaria filtration methods, and frequent water changes. The filtration found on most jellyfish aquariums includes a biological filter bed of bacteria. This is usually located in the sump and often times use the “old school” trickle filter and bioball design. More recent aquariums use sponge filters, floss, and sand beds. Some filtration methods are up for debate. Removing detritus and waste can be accomplished with filter socks and protein skimmers. 

Temperature ranges for most jellyfish are lower than that of tropical aquariums. While most hobbyists are familiar with a 74 to 82 degree Fahrenheit range they keep their fish at, moon jellyfish are often found in waters in the 50 to 70 degree range. 

To conclude

Jellyfish are an exciting new realm in the marine aquarium hobby. Some species are very challenging and yet to be seen in the hobby. Other species have been shown to be well suited for captive care and they are a welcomed addition to the hobby. Not only are jellyfish aquariums now available for purchase, but creating and building your own system is also an exciting project. All systems are unique and should be designed according to specific size, space, filtration, feeding and care requirements. The size of the aquarium will help to determine the types of jellyfish you can keep. The physical length and width of the tank will determine how much flow is needed. Also the number of jellyfish being kept will determine the amount of filtration needed.
