Keeping corals in a reef tank can be a fun experience. Even though it might take some time for you to properly maintain the corals and grow them to their full potential, the results can be quite rewarding.
The appeal and the popularity of the corals are very high, and it is easy to see why; some of them are really interesting and beautiful to look at, with some interesting colorations and growth patterns that can impress anyone.
When you think of a coral, you probably imagine the vivid colors of an ocean or of the Great Barrier Reef and the variety of different fish species that can be found in such environments.
There is no wonder that so many people are fascinated by coral reefs and want to recreate it in their own reef tank.
But owning a reef tank comes with its advantages and also difficulties. The important thing is that you thoroughly research the important information before you create a reef tank for yourself.
One of the most important and possibly one of the first decisions you would have to make is probably to decide what kinds of corals you will have in your reef tank.
When deciding for the right corals for your reef tank, you have to consider some things; firstly, you need to consider the size of the coral when it fully grows.
Then, you also need to consider how the coral looks and whether it would fit the fish in your tank. There are more types of corals to choose from.
Types of Corals
There are two types of different corals to choose from: the soft corals and the hard corals. What is the difference between the two and how to maintain each type of corals?
Hard corals are quite different from soft corals in the fact that they have hard, stony skeletons made of calcium. They are also called stony corals. Hard corals require special care within your aquarium; they can be quite demanding.
Hard corals need a strong lighting environment – 5 watts of light per gallon and also some supplemental minerals. Although they can be quite demanding and hard to keep, they also look really beautiful and unique.
Soft corals have a different structure than hard corals; they do not have stony skeletons based on calcium, but rather they have bodies made of soft tissues called the spiracles. Although they can be demanding to care for, they are less demanding than the hard corals.
Soft corals also need plenty of light (5 watts of light per gallon), and also mineral supplementation, but significantly less than the hard corals. One thing you do need to consider is that soft corals can reproduce quite fast and spread across the hard surfaces of the tank.
