Are corals difficult to keep in an aquarium?

Corals are among the most difficult animals to keep in an aquarium. They require extremely good water quality and water chemistry. They also require a proper amount of light and water flow. There are many different types of corals. Soft corals are the easiest to keep. They are more forgiving of water quality issues and do not need as much light as hard corals. Soft corals make a good choice for the beginner. Hard corals come in two types. Large Polyp Stony (LPS) corals are a bit easier to keep while Short Polyp Stone (SPS) corals can be extremely difficult to keep alive in an aquarium. SPS corals require bright lights, perfect water quality, and adequate water movement. SPS corals should only be kept by experienced reef aquarium hobbyists.
