What is the Difference Between LPS and SPS Corals?

🆚 Go to Comparative Table 🆚

The main difference between LPS (LarLarge Polyp Stony) and SPS (Small Polyp Stony) corals lies in their structure, skeleton, and care requirements. Here are the key differences between the two:

  1. Structure: LPS corals have larger polyps and a thick, fleshy skeleton, while SPS corals have smaller polyps and a thin, calcareous skeleton.
  2. Skeleton: LPS corals have a more porous skeleton, allowing them to absorb nutrients from the water more easily. In contrast, SPS corals have a more solid structure.
  3. Light and Flow: LPS corals generally require medium light conditions and moderate water flow, while SPS corals demand high-output lighting and considerable water flow.
  4. Care: LPS corals are considered easier to care for than SPS corals, making them more suitable for beginner aquarists. SPS corals, on the other hand, require more attention and care, but can create a stunning reef display for experienced aquarists.
  5. Placement: When mixing SPS and LPS corals in the same aquarium, it is crucial to plan their placement accordingly. SPS corals should be placed at the top to receive stronger lighting, while LPS corals prefer dimmer lighting.

It is possible to keep both LPS and SPS corals in the same aquarium, but maintaining an ideal environment for both can be challenging. For beginners, it is recommended to start with soft corals and gradually move on to hard corals like LPS and SPS once they have gained more experience.

Comparative Table: LPS vs SPS Corals

LPS (Large Polyp Stony) and SPS (Small Polyp Stony) corals are two types of calcareous corals that have different characteristics and requirements for growth in a reef aquarium. Here is a summary of their differences:

Feature LPS Corals SPS Corals
Polyp Size Large, fleshy polyps Small, flowery-looking polyps
Skeleton Structure Thick, fleshy skeleton Thin, calcareous skeleton
Water Currents Require slower and calm water currents Require faster and turbulent water currents
Light Requirements Need less light Need high light levels
Care Difficulty Easier to care for More difficult to care for
Habitat Provide shelter and food for fish and invertebrates Often used to create a natural habitat for other marine life

In terms of appearance, LPS corals have large fleshy polyps, while SPS corals have small polyps that cover the skeleton. LPS corals require less light and slower water currents, whereas SPS corals need high light levels and faster, turbulent water currents. LPS corals are generally considered easier to care for than SPS corals.
