Aquarium decorations are usually limited to pebbles, plants, rocks made of plastic and an aquatic sheet background that you stick behind your tank to create an illusion. But more than adding a bit of style to the tank, it also provides a nicer looking home for your aquatic pets, adding a bit of charm and beauty never hurt anyone. Speaking of adding charm, the moving jellyfish tank dÃ©cor is one of the more charming pieces of aquarium decoration available. Although it is artificial, this type of aquarium decoration is incredibly detailed and imitates a floating jellyfish. It works because it is following the movement of the water current inside the tank. You donât need to be afraid that it will float above water level because it is attached with a rubber suction pad at the end. These artificial jellyfish also boast a glowing effect because of the actinic lighting that is triggered by environment lights. As a result, the decor as a whole adds a unique atmosphere to your aquarium. Whatâs cool about this is that it is harmless to all your pet fish. The jellyfish tank decor is also ideal for those who want to have an aquatic pet but abhors the hassle or the mess. Having an artificial pet in your tank does not require cleaning or feeding, and you can also convince your friends that you have real pet jellyfish.
