Orange Tree Gorgonian for Your Saltwater Fish Tank

We all purchase coral for different reasons. Some of us purchase coral to make our takes look more like the ocean.

This coral is somewhat easy to keep alive as long as you have a good light in your tank. You can purchase different bulbs online from eBay. You can also try to find a good light from a local pet store near you. You will want the higest wattage bulb that you can get in order to keep coral alive. The Orange Tree Gorgonian will need to be placed at the top of your tank if you do not have a good lighting system. If you have a good light you can place this coral where it should go which is at the bottom of your saltwater tank. You will need to make sure that this coral is getting a good amount of water flow too.

If you have a canister filter you will want to adjust the power head to flow directly on the Orange Tree Gorgonian. If you cannot get a good amount of water to flow close to the coral you can purchase a wavemaker so that the water will flow in all directions instead of one direction. You can also point the power head towards the walls which will then bounce the water back towards your coral. The Orange Tree Gorgonian is a very colorful type of coral which can be easy to take care of if you have a good filter, good lighting system and the correct supplements.

Like other types of soft coral you will want to add iodine, trace elements, calcium and strontium to the water. Each bottle of supplement can be purchased from your local pet store and each bottle will cost you around $6 a piece but they will last you several months. You will need to add a cap full per 30 gallons. If you purchase a lot of different gorgonians you can keep them all together because they all need the same supplements. You will need to remove your coral from your fish tank before you medicate any of your fish in your tank. Corals cannot tolerate any types of strong medications.
