Jellyfish & Octopus Resources & Requirements

The only and best source of information for maintaining healthy jellyfish comes from the combined eight years experience of jellyfish aquarist Chad L. Widmer.

“How to Keep Jellyfish in Aquariums” is a complete book with detailed descriptions of everything to know from how to build a jellyfish aquarium to the specific feedings and maintenance of 14 common jellyfish.

Chad L. Widmer has worked in the Monterey Bay Aquarium with more than 20 aquarists maintaining jellyfish.

We recommend anyone interested in keeping jellyfish to read this book.

The book can be ordered from:
www.amazon.com

All the animals that are offered on this website are from the Canadian side of the pacific ocean.

The consistant water temperature that must be maintained in a jellyfish aquarium is 18 degrees/ 64.4 fahrenheit.
To achieve this a chiller must be added to the tank.

We recommend a chiller with the capabilities and the strength to be able to reach a lower temperature then the normal required 18 degrees as chilling needs will change from summer and winter seasons.

www.marinedepot.com is a currently a good source for aquarium supplies.

There are two chillers that we recommend for a standard small 35gal tank up to a larger tank up to 80 gal.

AquaEuroUSA Max Chill 1/10 HP Aquarium Chiller For Tanks Up To 80 Gallons

AquaEuroUSA Max Chill 1/13 HP Aquarium Chiller For Tanks Up To 50 Gallons
Tank Size Up To: 50 Gallons

Salt content of water must be 1.0165
Testing of salt content can be done with a hydrometer

The natural ocean water in which the jellyfish come from have chemical conditions of the following:
Gh 180
Kh 80
pH 6.9
N02 1-2
N03 20-40
Testing of the water conditions can be done with aquarium test strips or drops.

After changing your water with ONLY distilled bottel water if needed you may find your acceptable water results are:
Gh 180
Kh 80
pH 7
N02 0
N03 0

To maintain such a temperature a chiller must be installed on a tank that is at least 35 gallons. The size of the aquairum also dependson the type of chiller used. The a large tank is needed because the GPH (water flow). The high flow rate of water that normally runs through a chiller must be buffered.

The water must be buffered so that a calm cold environment can exist for the jellyfish. A smaller tank will require a sub tank for this purpose.

There will be a lot of wasted food when feeding jellyfish. Only a small portion of food will actually make it into the stomachs of the jellyfish. To clean up the food it is best to instal a canister filer system that will suck up the food when it falls to the bottom of the tank. We recommend a Eheim Classic External Canister Filter. Make sure that the intake flow of water has a tube to run right up to the surface of the tank. This is to prevent any bubbles from getting stuck inside jellyfish.

Octopus Resources & Requirements

Water conditions and requriments are the same for octopus except the salt content of the water should be 1.0225

One of the best resources for keeping octopus as pets are the research efforts by
Robert J. Toonen, PhD.

Robert J. Toonen's impressive education consists of:
- PhD Population Biology, University of California, Davis
- MS Marine Sciences, University of North Carolina, Wilmington
- BSc Honours Zoology, University of Alberta, Canada
