Purple Stylophora (Cats Paw)

Purple Stylophora (Cat’s Paw) Coral Frag

The Purple Stylophora, commonly known as Cat’s Paw, is a hardy and visually appealing SPS coral recognised for its compact branching structure and rich purple colouration. With its thick, stubby branches and excellent polyp extension, this coral adds texture, depth, and reliable colour to reef aquariums.

Often recommended as one of the best SPS corals for reef keepers transitioning from LPS to SPS, Purple Stylophora offers strong growth and resilience without sacrificing visual impact.

Natural Habitat & Distribution

Stylophora corals originate from the Indo-Pacific region, where they are found across:

• The Great Barrier Reef, Australia

• Indonesia

• Fiji and Tonga

• The Red Sea

• Central and Western Pacific reef systems

In the wild, Stylophora species inhabit shallow reef flats and upper reef slopes, exposed to strong sunlight and moderate to strong water movement—conditions reflected in their aquarium care requirements.

A Brief History

Stylophora has long been favoured in the reef-keeping hobby for its durability, fast growth, and tolerance compared to many Acropora species. The Cat’s Paw variety gained popularity due to its dense, rounded branching form and ability to maintain colour under a wide range of reef conditions.

Purple Stylophora remains a staple SPS coral, valued for its reliability and classic reef appearance.

Appearance & Growth

Classified as an SPS (Small Polyp Stony) coral, Purple Stylophora develops a compact, bushy branching growth form, with thick branches that resemble the shape of a cat’s paw.

• Deep purple to violet colouration

• Thick, rounded branch tips

• Strong polyp extension under stable conditions

Growth is fast and forgiving, making it ideal for building reef structure.

Placement & Lighting

Purple Stylophora performs best under medium to high lighting, closely mimicking its natural reef environment.

• Lighting: Medium–High

• Best placed in the mid to upper sections of the aquarium

• Lower light may reduce colour intensity

Flow Requirements

Provide moderate to strong, random flow to support healthy growth, polyp extension, and to prevent detritus accumulation between branches. Avoid harsh, direct laminar flow.

Water Chemistry

Stylophora benefits from stable reef parameters. Maintain consistent levels of:

• Calcium

• Alkalinity

• Magnesium

Along with balanced trace elements and stable nutrient levels. Regular testing and dosing are recommended.

Feeding

Primarily photosynthetic, Purple Stylophora can benefit from occasional supplemental feeding such as:

• Fine powdered coral foods

• Micro-plankton blends

Light feeding can enhance growth and overall vitality when used sparingly.

Temperament & Spacing

Stylophora corals are generally peaceful, but their bushy growth requires adequate spacing to prevent contact with neighbouring corals as they expand.

Frag Size & Natural Variation

• Frag size: Approximately 1 inch

• Each frag is unique and may vary slightly in shade and branch structure depending on lighting and tank conditions.

Care Summary

• Care Level: Moderate

• Flow: Medium–High

• Lighting: Medium–High

• Temperament: Peaceful
