Still very blur

[dominik]

Pai seh, now still blur about what is hard and soft coral? what is LPS and SPS? Anyone can provide pictures to describe the different types?

In general, the Small Polyped Stony corals have small polyps on a calcerous skeleton. In many instances they are either branching or plated. SPS corals are generally considered more difficult to keep than the LPS or soft corals and are not recommended for beginners.

Large Polyp Stony Corals are generally larger calcareous corals with large fleshy polyps. The degree of extension of the tentacles depends upon the amount of light, current, and whether the coral is feeding or not. Most of the LPS corals produce long sweeper tentacles which they use to keep any other organisms a safe distance away.
