General Questions About Jellyfish FAQ

Yes! All the jellyfish we sell are absolutely real, and not the plastic jellyfish toys. These jellyfish eat, move, and live.
Well, technically, yes. But depending on the species, you might not actually be able to feel the sting. Species such as the moon jellyfish do not have a sting noticeable to human touch. However, a species like the Australian box jellyfish, well those have a sting you can most certainly feel!
Yes and no. Jellyfish grow with how much food they're given. If given lots of food, your jellyfish will grow quite big quite quickly! But if you give your jellyfish the recommended amount of food (less than 1/8th of a teaspoon) once a day, there won't be any problems.
Depending on the species, they can live from 6 months to (in some cases) 2 years. Our moon jellyfish, our most popular species of jellyfish, usually lives for 1 year.
Unless stated otherwise, all of our jellyfish are saltwater.
All of our jellyfish are shipped from Hong Kong. In Hong Kong, almost all of our jellyfish are grown in captivity.
Absolutely not. If you do this, your jellyfish will sting each other to death, and eat each other.
Again, the sad fact is that your jellyfish will sting your other fish to death, or become a tasty snack for your other fish! In addition, jellyfish need specialized aquariums with a particular flow pattern to survive. Though that might sound intimidating, all of the aquariums we provide are designed with jellyfish in mind.

Water Quality

No. The best water to use for jellyfish is reverse osmosis deionized (RODI) water. Other water is likely to contain trace amounts of minerals that are toxic to jellyfish. Jellyfish are over 95% water, so they are despite being easy to care for, they are also quite fragile! They are very sensitive to polluted water.
Optimally, 0 traces of ammonia, nitrites or nitrates. Of course, this isn't always possible. With a cycled aquarium, you should never exceed 1ppt of ammonia of nitrite. If you do, there's a serious problem with your water chemistry. However, a few nitrates aren't the end of the world. Jellyfish will do fine until there are 20ppt nitrates in the water, at which point their health will begin to deteriorate.
Excellent question! The best answer to this question is covered in our blog 'The Nitrogen Cycle'. This blog will clearly explain the importance of water, and how to keep your aquarium clean. It will also fully outline the cycling process for you.

Jellyfish Care FAQ

No! Not at all. In fact, many report that keeping jellyfish is actually very easy compared to keeping a full saltwater aquarium! Of course, there are still some important tasks for the budding jellyfish aquarist. Jellyfish need clean reverse osmosis deionized (RODI) water mixed with aquarium safe salt, and fed their proper food once a day.
It's a lot more simple than you'd expect. The best advice is to treat them like any other fish tank. Provide them clean RODI water mixed with aquarium salt, feed them once a day, and change some of the water (about 25%) once a week. Just make sure that the salinity of the water (how salty the water is) and how warm the water is stays consistent. Jellyfish are over 95% water, so keeping your water stable and clean is really important!
In the wild, jellyfish will really eat anything that fits into their (tiny) mouths. This really means mostly zooplankton and tiny fish. In captivity, we provide them a mixture of dry, live, and frozen food to keep them full and happy.
By and far the moon jellyfish. We have a whole article you can read about moon jellyfish in our jellyblog, so be sure to go over there to read more about our favorite species of jellyfish!
No. Some jellyfish eat other jellyfish as prey. In general, jellyfish will sting each other to death and eat each other. However, if kept among their own species, this doesn't happen.

Website and Ordering

Jellyfish are not shipped with the tank, no. Instead, we issue a virtual coupon to you within a week of purchasing the tank. With this coupon, you can redeem the code in the shopping cart to have a free jellyfish of a specified size shipped to your door. The coupon must be redeemed within three months of the purchase of the tank, or it will expire. Shipping is not included in the coupon.
Live jellyfish are shipped in a Styrofoam box with a heat pad included. The Styrofoam box is then placed in a marked cardboard box to be sent out using UPS overnight shipping.
Yes. You can find out more on our Arrive Alive guarantee, though this does not apply to delayed mail.
For a shipping quote, go to the website and put the items you are thinking about ordering in the site's shopping cart/bag and hit check-out. Put in your postal code and it'll figure it out for you If you are just looking to find out the shipping rates, there is no need to enter payment information.
All livestock is shipped via UPS Express. Unfortuniatly, UPS does not deliver to Post Office Boxes. If your address is a PO Box, in order to receive jellyfish, you will need to arrange to have them delivered to a either a street address (if available) or a UPS Access Point, Depot or UPS Store (location info is available on the UPS website). Find a location that works for you and make a not in the ‘Order Comments’ field during checkout on our website. If this is your situation, be aware that you will need to pay for your order via Interac eTransfer! Because of security policies, we are only able to ship orders paid via credit card to the billing address associated with the credit card used.
There are a couple things that we can do. The simplest is to have the jellyfish delivered / held(for pick-up) at a UPS Store close to you. You’ll be able to go and pick up the jellyfish at your leisure (note the facilities hours of operation). A big advantage of this is that the UPS Stores are heated & air conditioned, so the problems with overheating / freezing in the trucks are minimized. To have your jellyfish shipped to a UPS Store, use your regular address as the shipping address on the order (DO NOT use the UPS Store address). The in the Order Notes feild, indicate that you would like have your jellyfish Help For Pick-up at a UPS Store and put the UPS Store location ### and address in the notes field. Alternatively, if you work in a place that can receive deliveries, we can ship the jellyfish to your workplace. Don’t worry about working to the end of the day with the jellyfish there. They are fine in the shipping bags for extended periods of time if they are kept at room temperature. As per our credit card security restrictions, orders shipped to an address not a credit card billing address will NEED to be paid via Interac e-Transfer.
Unfortunately, because we operate out of a residential building, we prefer not to have people come to visit. However, we will make exceptions to local pick ups that we have scheduled.
Different aquariums come with different supply and accessory packages. You’ll need to check the produce description of the individual aquarium you are interested in to see what it comes with. The basic starter kits contain pretty much all of the supplies that come in the quarterly packages as well as the accessories you'll need to care for your jellyfish and maintain their aquarium. Other recommended items are... test kit/strips, algone, prime(detoxifies ammonia in emergency situation) and brine shrimp eggs (newly hatched brine shrimp are by far the best food for your jellyfish). If you want to be able to measure the salinity more accurately than the simple hydrometers allow, consider a refractometer.
On our website! There are plenty of care kits and products that we offer to help you be the most successful you can be with your jellyfish.
