The Joy of Jellies: Caring for Jellyfish in Your Home Aquarium
Caring for fish is a personally satisfying hobby, and adding exotic jellyfish to your collection is uniquely rewarding. Though not for everyone, caring for jellies creates a mesmerizing addition to your home, and makes for interesting conversation as you watch these living works of art float and sway. But caring for jellyfish in your home aquarium requires that you do your research well in order to fully understand these fascinating creatures before you bring them home.
Jellyfish are made up of over 95% water, and most do not have a spine, heart, stomach, specialized digestive system, eyes, or brain. They require a specifically designed environment to live and flourish in captivity, and though expensive, jellies are worth the extra effort and higher price tag under the right circumstances.
Below are two you will need in order to keep your jellyfish safe, healthy, and happy, but keep in mind that most of the supplies for jellyfish will need to be purchased online, since they aren’t usually sold by fish supply stores.
A Proper Haven
Jellyfish cannot be housed in a traditional rectangular fish tank because they need a constant flow of water that imitates the ebb and flow of ocean currents. This constant flow will keep your jellies from getting trapped in a corner or pulled into the circulation system. Along with a circular tank, you will need to cover your water pump and skimmer tubes with a thin mesh material that will prevent the jellies from getting sucked in. You can find pumps and skimmers designed specifically for jellyfish.
It’s important that no rocks, hard materials, or tank decorations go into your tank because a small bump against these items could damage your delicate jellies. Place a small amount of aquarium gravel in the bottom of the tank, but cover it with a one inch layer of glass marbles. This will prevent the jellies from hurting themselves on the sharp gravel. Use a porous type of gravel to retain beneficial bacteria inside.
While you can place your take anywhere in your home, you will want to make sure it is out of direct sunlight and away from electrical equipment and heat sources.
Install the aquarium heater by submerging it into the water, then plugging it in. Research the required temperature for the type of jellyfish you have, but with most jellies, the correct temperature is 77 degrees. Install a vertical bubble tube to create proper water circulation, then fill your tank with high-quality salt water to about two inches above the top of the bubble tube. Make sure that the water is below the light bulb, though, so the water doesn’t get overheated by the light.
Baby jellyfish eat lots of small brine shrimp that are 1-2 days old, and adult jellies eat adult brine shrimp. One teaspoon of brine shrimp into the aquarium once a day should provide enough food for your jellies. If your species of jellies eats algae, feed them daily with a pea-sized amount of algae-based jellyfish food from an online aquarium supply store.
