Green Slimer Acropora Coral

Green Slimer Acropora Coral (Acropora yongei)

The Green Slimer Acropora Coral is a classic SPS coral known for its intense neon-green coloration, long branching growth, and excellent polyp extension. Its bright color and fast-growing branching structure make it a popular Acropora for adding height, texture, and vivid contrast to an established SPS reef aquarium.

Green Slimer Acropora is known for being relatively hardy compared with many other Acropora varieties, making it a good introduction to Acropora for reef keepers who already have experience maintaining stable SPS conditions. It performs best with strong reef lighting, high random water flow, and consistently stable water chemistry.

Recommended Care

• Scientific Name: Acropora yongei
• Common Name: Green Slimer Acropora
• Care Level: Moderate to Advanced
• Lighting: Moderate to high, approximately 200–350 PAR
• Water Flow: High — strong, random, turbulent flow
• Placement: Middle to upper areas of the aquarium
• Temperament: Generally peaceful, but provide adequate room for branching growth and competition with neighboring corals
• Feeding: Primarily photosynthetic; naturally available plankton and occasional fine particulate coral foods may supplement nutrition
• Growth: Moderate to fast under stable conditions
• Reef Safe: Yes

Water Parameters

• Temperature: 75–79°F
• Salinity: 1.024–1.026 SG
• Alkalinity: 8–10 dKH
• Calcium: 400–450 ppm
• Magnesium: 1,250–1,400 ppm

Green Slimer Acropora performs best when reef parameters are kept consistently stable. Gradually acclimate the coral to intense lighting and strong flow rather than immediately placing a new frag in the highest-light area of the aquarium. Green coloration and fluorescence can vary depending on lighting spectrum, intensity, nutrients, and aquarium conditions.
