LPS vs. SPS Corals: Which is Right for Your Reef Tank?

Corals are the stars of any reef tank and choosing between LPS (Large Polyp Stony) and SPS (Small Polyp Stony) corals is an important decision for any reefer. Each type offers unique beauty and challenges, making it essential to understand their care requirements before deciding which is right for your reef. This guide breaks down the differences between LPS and SPS corals, helping you choose the best fit for your tank based on your experience level, equipment, and goals.

What Are LPS Corals?

LPS corals are known for their large, fleshy polyps and vibrant colours. They are a Favorite among beginner and intermediate reefers due to their hardiness and tolerance of fluctuating water parameters.

• Size: LPS corals have larger polyps compared to SPS corals, and their soft, fleshy appearance makes them stand out in any reef tank.
• Growth Rate: LPS corals grow slower than SPS, but their larger size and long tentacles create a more substantial, dramatic presence.
• Care Requirements: These corals are more forgiving when it comes to water quality and lighting, making them easier to care for. They can thrive under moderate lighting and flow.
• Common Examples: Popular LPS corals include Hammer Coral, Torch Coral, and Acanthophyllia.

Pro Tip: LPS corals are excellent for reefers who want to add movement and colour without the need for high-end lighting and water flow.

What Are SPS Corals?

SPS corals, on the other hand, are characterized by their smaller polyps and rigid skeletal structure. While they may not have the fleshy look of LPS corals, SPS corals are prized for their intricate branching structures and vibrant colour variations.

• Size: SPS corals are smaller, with compact polyps and a dense, stony structure.
• Growth Rate: SPS corals typically grow faster than LPS corals, rapidly expanding into complex, tree-like formations.
• Care Requirements: SPS corals require pristine water quality, stable parameters, high lighting and strong water flow. They are more sensitive to fluctuations in salinity, alkalinity, and nutrient levels.
• Common Examples: Popular SPS corals include Acropora, Montipora, and Birds nest.

Pro Tip: SPS corals are ideal for experienced reefers who have advanced equipment and can maintain consistent water parameters.

LPS vs. SPS: Key Differences

Here’s a side-by-side comparison of LPS and SPS corals to help you determine which type best suits your reef tank:

Pro Tip: If you’re just starting out, LPS corals are easier to manage and are more forgiving in terms of tank parameters. For more advanced reefers who are willing to move up in the coral world, SPS corals provide stunning growth formations and vibrant colours with a different challenge.

Which Is Right for You?

Choosing between LPS and SPS corals depends on several factors, including your experience level, equipment, and the amount of time you can dedicate to maintenance. Here’s a quick guide to help you decide:

• LPS Corals are perfect if:
• You’re new to reefing or have an intermediate level of experience.
• You want a lower-maintenance reef tank.
• You prefer corals with large, flowing tentacles that sway with water movement.
• Your lighting and water flow systems are moderate.
• SPS Corals are ideal if:
• You have advanced reefing experience and can maintain stable, pristine water parameters.
• You’ve invested in high-end lighting and water flow systems.
• You enjoy the challenge of growing intricate, branching coral structures.
• You can consistently test and monitor water chemistry.

Pro Tip: You can combine both LPS and SPS corals in a mixed reef but be sure to place them in zones that match their respective lighting and flow needs.

FAQ:

• Can I mix LPS and SPS corals in the same tank?
  Yes, many reefers keep LPS and SPS corals in a mixed reef. Just make sure to place the SPS corals in areas with higher lighting and water flow, while keeping LPS corals in more moderate zones.
• Which type of coral grows faster, LPS or SPS?
  SPS corals generally grow faster than LPS corals. If rapid growth is a priority, SPS may be the better choice for you.
• Are LPS corals easier to keep than SPS?
  Yes, LPS corals are generally easier to care for, as they are more tolerant of fluctuations in water parameters. SPS corals require more precision and stable conditions.

LPS and SPS corals each bring something unique to a reef tank. LPS corals are perfect for reefers who want to enjoy a lower-maintenance setup with beautiful, large polyps and vibrant colours. SPS corals, on the other hand, offer a more challenging experience but reward you with stunning growth formations and bold, intricate structures. Whichever you choose, be sure to cater your reef setup to their specific needs for the best results.
