There is always something that draws people to the water—maybe its charm, the mystery, or simply because of the peacefulness that it openly radiates. As we normally see on tv or in the books, seas and oceans are huge bodies of water that are full of amazing living creatures. There are over a million of living species in the ocean and scientists continue to discover more and more of them in this lifetime. Marine life is colourful and abundant—it’s like a whole new different world out there. A lot of marine enthusiasts take their love for the ocean into their homes and decide to set up their own saltwater aquariums as a hobby or as part of their interior design. People would normally think that keeping a saltwater aquarium is very hard to maintain but presently, it’s not as hard as how it used to be. Like most hobbies, it may require a lot of things to start and may involve some considerations.
The most exciting part is choosing the marine life for your aquarium. Aside from the fishes, it is fundamental to add corals to your saltwater tank. When you decide to set up your own aquarium at home, choosing the right coral is also very important. There are several types of coral that you may not know about and you need to research about the different types of corals for a good start.
Corals can be classified mainly into two main types: hard or soft.
Soft corals as the name suggests, are soft-bodied marine animals with no solid protective skeleton which make them more flexible. Coming from the Alcyonacea order, this type of coral is fleshy and has eight feathery tentacles with spiny sclerites that are used to dissuade predators. This type of coral is usually bright-coloured and jelly-like, and has a swaying figure that resembles plants. Soft corals can expand and retract. These corals come in several different colors and shapes. They are good for reef tanks as they are adaptable to low-light conditions. Popular soft corals among aquarium hobbyists include Zoanthids, which is also referred to as the soft coral superstar, and Palythoa which is a colonial type coral like the Zoanthids.
Common types of soft coral
- Gorgonian (Sea Fans)
- Carnation coral
- Toadstool coral
- Bubble coral
- Tree coral
- Sea Pens
Hard corals, also called Scleractinia or Stony corals, are rock-like marine animals that build hard skeletons made of calcium carbonate for themselves. This type of coral is also referred to as the “reef-building coral” because they grow in colonies and create and maintain the hard layer in coral reefs. While soft corals have eight tentacles, hard corals, on the other hand, only have six. Hard corals are known to have a symbiotic relationship with the algae called zooxanthellae, which provides them with food, and in return use the corals as shelters.
