Frequently Asked Questions

Why are some jellyfish out of stock for long periods of time?


Our goal at the Jellyfish Warehouse is to provide a variety of jellyfish, most of which are not sold elsewhere. This requires that some jellyfish be collected on our collection trips. Many jellyfish

are seasonal, and sometimes they just aren't there when you think they will be.



Do you harm the natural jellyfish populations when you collect them to sell?


No. Jellyfish are found in huge populations, and are now thought to be overpopulating. They deplete plankton and fish egg populations. In recent years, giant swarms of jellyfish have clogged water intakes for nuclear reactors and hurt major fish populations. Collecting jellyfish to sell as pets is a eco-friendly way of using jellyfish for good, as opposed to destroying excess jellyfish.



Are the jellyfish guaranteed to arrive alive?


A: Our jellyfish are always guaranteed to arrive alive. If something happens to your jellyfish on the way to you, send us pictures or video and we would be happy to replace it, if you pay shipping.



How are the jellyfish shipped?


Jellyfish are double bagged in fish shipping bags, which are rubber banded. These bags are then packed inside an insulated box. Your jellyfish will be shipped overnight.



Why can't I just buy a regular aquarium for my jellyfish?


Jellyfish are delicate creatures. Many of them need to be suspended in water at all times. Those that don't, still need careful filtration. Most filters will blend your jellyfish up. The Jellyfish Warehouse makes sure to produce affordable tanks specially for your jellyfish.



Can I feed my jellyfish frozen Cyclops foods?


A: No, this variety of food has been shown to cause major size reduction in healthy jellyfish (they don't need a slim figure!). Many foods are good for jellyfish, but frozen cyclops is not one of them.



Why is my jellyfish inside-out?


This is known as eversion. Jellyfish are fairly sensitive to temperature or chemical shock. Make sure your water quality is good. Make sure the temperature is within their preferred range. Most eversion cases are from temperatures that are too high. Your jellyfish may return to its normal shape once the water quality is in check. If not, try slowly bringing up the salinity until its in the higher end of their operating range (don't overshoot!)



Can you get a certain jellyfish species for me?


That depends on what it is. Contact us with the species you are looking for, and we will see if we can obtain it. We do not sell any lethal jellyfish.


Will my jellyfish breed in their tank?


If you have a male and female jellyfish, it is possible they will breed in your tank. Many jellyfish we stock have not bred in captivity before. Comb jellyfish are hermaphroditic and can fertilize their own eggs. Comb jellyfish breeding has not been largely successful, however.



What happens if jellyfish breed in my tank?


That all depends. You will likely see the longer lived stage of most jellyfish, the polyp. Polyps are small buds with tentacles, that grow on surfaces. Under certain conditions, polyps will shoot off jellyfish babies (ephyra). The Master Jellyfish Tank may be able to house these free swimming babies. If you find polyps in your jellyfish chamber, scrape them off. They can sting adults and cause harm. If you carefully scrape them off, you can move them to a dish or bowl, where they may reattach.

The Jellyfish Warehouse is based in  North Carolina. We're the only retail company to sell live jellyfish and tanks on the east coast that is run by hobbyists, not businesspeople. We care about our jellyfish–and the customers they live with!
