Coral keeping is the showpiece of marine aquariums, but care difficulty varies significantly by species. For beginners, it's recommended to start with hardy soft corals, then gradually progress to LPS and SPS as you gain experience. This article introduces popular corals in a guide format, explaining their characteristics and care tips.

Coral Classification and Care Difficulty Guide
Corals are broadly classified into three groups.
Group
Characteristics
Care Difficulty
Representative Species
Soft Corals
No skeleton, soft-bodied. Relatively tolerant of water quality fluctuations
Beginner-friendly
Disc corals, star polyps, mushroom corals
LPS (Large Polyp Stony Corals)
Calcareous skeleton. Large, fleshy polyps
Intermediate
Flower pot corals, flowing corals, bubble corals
SPS (Small Polyp Stony Corals)
Calcareous skeleton. Small, delicate polyps
Advanced
Acropora, Montipora
Since each group has different requirements for light intensity, water flow, and water quality stability, starting with a group that matches your tank setup and experience level is the shortest path to success.

Soft Corals: Species Recommended for Beginners
Star Polyps
Care Difficulty: ★☆☆☆☆ (Very easy)
Lighting: Low to moderate light intensity acceptable
Water Flow: Weak to moderate
A beautiful coral that spreads in a green mat-like form and opens star-shaped polyps. With rapid growth that spreads across live rock, it can create a green carpet in your tank in a short time. It's relatively tolerant of poor water conditions, making it ideal as your first coral. However, its fast growth can encroach on other corals' space, so the trick is to place it on an isolated rock to control its spread.
Disc Corals
Care Difficulty: ★☆☆☆☆ (Very easy)
Lighting: Low light intensity acceptable
Water Flow: Weak
A flat disc-shaped coral with an extremely wide range of color variations—red, blue, green, and purple. It reproduces naturally through division, so you may find the number increasing before you know it. It dislikes strong light and strong water flow, so place it in rock crevices or the lower part of the tank. Different impressions depending on species like Ricordea and Rhodactis, making it highly collectible.
Mushroom Corals
Care Difficulty: ★★☆☆☆ (Easy)
Lighting: Moderate light intensity
Water Flow: Moderate
A mushroom-shaped coral with an endearing appearance as it extends polyps from the cap. Relatively tolerant of water quality fluctuations, it's popular as a beginner's first coral. It has a habit of shedding a mucus layer periodically, but this is normal behavior and nothing to worry about. Propagation through fragging is relatively easy, making it ideal as an introductory species for coral propagation.
Zoanthids
Care Difficulty: ★☆☆☆☆ (Very easy)
Lighting: Low to moderate light intensity
Water Flow: Weak to moderate
The greatest appeal is its extremely wide range of colors and high collectibility. It reproduces rapidly and under good conditions can grow to cover the entire surface of live rock. Important note: some Palythoa species contain palytoxin, a toxin, so wear rubber gloves and protective eyewear when performing fragging work.

LPS: Popular Species for Intermediate Keepers
Flower Pot Corals
Care Difficulty: ★★★☆☆ (Moderate)
Lighting: Low to moderate light intensity / Water Flow: Weak
Characterized by large, fleshy polyps that inflate dramatically, with vibrant colors in red, green, and orange being popular. The sight of them inflating in response to feeding is impressive, and the ease of placing them directly on the substrate makes them ideal for LPS beginners.
Flowing Corals
Care Difficulty: ★★★★☆ (Somewhat challenging)
Lighting: Moderate light intensity / Water Flow: Moderate
A beautiful coral with rounded, separated polyps that sway as if flowing. Its skeleton is fragile, so careful handling is necessary. It's prone to Brown Jelly infection, so take immediate action if you notice any abnormalities. It uses sweeper tentacles to attack surrounding corals, so maintain a distance of at least 10cm.
Bubble Corals
Care Difficulty: ★★☆☆☆ (Easy)
Lighting: Low to moderate light intensity / Water Flow: Weak
An LPS with large inflated polyps that create impressive volume. Hardy for an LPS and well-suited for your first LPS. It can be placed directly on the substrate and responds well to feeding.

SPS: Stunning Species for Advanced Keepers
Acropora
Care Difficulty: ★★★★★ (Difficult)
Lighting: Strong light intensity essential / Water Flow: Strong random flow
Considered the pinnacle of coral keeping, with unrivaled color beauty. Maintaining water quality (KH, calcium, and magnesium stability) is critically important, and high-performance lighting and a protein skimmer are essential. The sense of accomplishment when successful is exceptional, and it's the ultimate goal for many aquarists.
Montipora
Care Difficulty: ★★★★☆ (Somewhat challenging)
Lighting: Moderate to strong light intensity / Water Flow: Moderate to strong
Easier to keep than Acropora, it's popular as an SPS starter. Many species grow in plate or encrusting forms with diverse colors in purple, red, and green.
SPS keeping requires a well-established system, so gain sufficient experience with soft corals and LPS before attempting it.

How to Choose and Purchase Corals
When purchasing corals, consider not just care difficulty but compatibility with your tank environment. Specifically, confirm beforehand that your lighting type and PAR value, water pump output, and water quality parameters (KH, Ca, Mg, NO3, PO4) match the coral's requirements. When ordering online, check photos from multiple angles and request images under white light in addition to blue light to get a better sense of actual coloration. Choose healthy specimens with polyps that open well, uniform color, and no bleaching or browning.
Post-introduction care is equally important. After acclimating new corals, temporarily place them in a location with gentle light and water flow, such as the tank bottom or rock crevices. Gradually move them to their target position over 1-2 weeks in a process called "light acclimation" to minimize stress from environmental change.
