Red Convict Chalice

About this coral

Red Convict Chalice is a Large Polyp Stony (LPS) coral sold as a chalice. In an aquarium, it’s a visually distinctive centerpiece coral known for its textured “chalice” form and inviting look under reef lighting—especially when you provide gentle, stable husbandry so the colony can remain open and active.

Features:

• Chalice-style LPS texture adds depth and a sculptural focal point to reef aquascapes.
• General husbandry approach: start in modest light with indirect flow to help the coral acclimate and maintain tissue comfort. ([reefcultureco.com](https://reefcultureco.com/pages/chalice-coral-care-guide?utm_source=openai))
• Keep water movement on the gentle/moderate side—aim for enough flow to prevent debris settling, without blast-like laminar jets. ([topshelfaquatics.com](https://topshelfaquatics.com/pages/corals/miami-hurricane-chalice-coral?utm_source=openai))
• Placement in the lower-to-middle tank zone supports moderate light needs while avoiding unnecessary intensity stress. ([marineconceptsupply.com](https://www.marineconceptsupply.com/blogs/news/chalice-coral-care-guide?utm_source=openai))
• Provide stable “core” reef parameters (alkalinity, calcium, magnesium) as chalices rely on consistent mineral availability for calcification.
• Chalice corals benefit from occasional target feeding; at night, they may extend feeding structures and accept small meaty foods. ([kinstation.com](https://www.kinstation.com/encyclopedia/chalice-coral?utm_source=openai))

Specifications:

• Care level (general guidance): Moderate (start with modest/low-to-moderate light and gentle to moderate flow). ([topshelfaquatics.com](https://topshelfaquatics.com/pages/corals/miami-hurricane-chalice-coral?utm_source=openai))
• Lighting: Low to moderate / indirect; acclimate gradually. ([topshelfaquatics.com](https://topshelfaquatics.com/pages/corals/miami-hurricane-chalice-coral?utm_source=openai))
• Water flow: Low to moderate; avoid direct blasting; moderate flow is preferred. ([topshelfaquatics.com](https://topshelfaquatics.com/pages/corals/miami-hurricane-chalice-coral?utm_source=openai))
• Placement: Lower to mid-tank. ([marineconceptsupply.com](https://www.marineconceptsupply.com/blogs/news/chalice-coral-care-guide?utm_source=openai))
• Target temperature: 76–79°F (24–26°C). ([reefcultureco.com](https://reefcultureco.com/pages/chalice-coral-care-guide?utm_source=openai))
• Salinity (specific gravity): 1.025–1.026. ([topshelfaquatics.com](https://topshelfaquatics.com/pages/corals/miami-hurricane-chalice-coral?utm_source=openai))
• Alkalinity (dKH): ~7–9 dKH. ([reefcultureco.com](https://reefcultureco.com/pages/chalice-coral-care-guide?utm_source=openai))
• Calcium: ~400–450 ppm. ([reefcultureco.com](https://reefcultureco.com/pages/chalice-coral-care-guide?utm_source=openai))
• Magnesium: ~1,250–1,400 ppm. ([reefcultureco.com](https://reefcultureco.com/pages/chalice-coral-care-guide?utm_source=openai))
• Feeding (optional, general guidance): Target-feed 1–2 times per week with small meaty foods such as mysis or finely chopped seafood. ([kinstation.com](https://www.kinstation.com/encyclopedia/chalice-coral?utm_source=openai))
