Orange Krak Zoas

About this coral

Orange Krak Zoas are zoanthid/polyps for reef aquariums, sold as live colonial polyps that attach to rock or frag plugs. They’re commonly kept for their colorful, low-profile colonies and ability to spread across suitable rockwork, making them a popular choice for adding hardy, eye-catching color to reef displays. As zoanthids are colonial animals, the practical way to use them in a tank is to place them on stable, well-lit rock where they can gradually expand without being shaded or smothered by faster-growing neighbors.

Features:

• Colonial, soft-bodied polyps that form attractive reef “patches” over time
• Typically considered hardy for established reef tanks when basic water conditions are stable
• Receives energy from their photosynthetic symbionts, so lighting is a key part of maintenance
• Usually prefers gentle to moderate water movement to keep tissue clear of debris
• Works well on rockwork and frag-style surfaces for aquascape-focused placement

Specifications:

• Care level (general zoanthid guidance): Moderate; best results in stable, established reef systems
• Lighting (general zoanthid guidance): Moderate to bright aquarium light
• Water flow (general zoanthid guidance): Low to moderate, with indirect, non-blasting circulation
• Placement: Attach/place on stable rock or a frag plug where polyps can expand gradually
• Diet: Mostly supported by light; can also benefit from dissolved and fine particulate foods
• Temperature: Typical reef range: about 72–78°F (22–26°C)
• Salinity: Typical reef range: about 1.024–1.026 SG
• pH: Typical reef range: about 8.1–8.4
• Adult size: Colony size varies widely depending on space, light, and water stability
