Bali Slimer Coral (Acropora yongei) Frag

The Bali Slimer is one of the most recognizable SPS corals in the reef hobby, famous for its bright green coloration, thick branching growth, and rapid growth rate. It gets its nickname from the protective mucus it produces when handled, making it a hardy and rewarding Acropora for reef keepers looking to keep SPS corals.

LIGHTING

Moderate to high lighting is essential. Bali Slimers thrive under strong reef lighting and tend to develop their best colour and fastest growth when provided with consistent, high-quality lighting.

FLOW

Strong, turbulent water flow is important. Like most Acropora, Bali Slimers prefer plenty of random flow to keep their branches clean, prevent detritus buildup, and support healthy growth.

FEEDING

Bali Slimers receive most of their energy from light through their symbiotic algae. While direct feeding is not required, occasional feeding of fine coral foods, amino acids, or reef supplements can help promote growth and coloration.

PLACEMENT

Typically placed in the middle to upper sections of the rockwork where they can receive strong light and flow. New frags should be introduced carefully and gradually acclimated to brighter conditions if necessary.

WATER QUALITY

Stability is key to long-term success. Consistent alkalinity, calcium, magnesium, salinity, nutrient levels, and temperature are essential for maintaining healthy tissue, strong growth, and vibrant colour.

TANK MATES

Bali Slimers are generally peaceful but should be given adequate space to grow. Their branches can quickly expand and may shade or come into contact with neighbouring corals if not managed.

MAINTENANCE

Due to their fast growth rate, Bali Slimers may require occasional fragging or pruning to maintain their shape and prevent overcrowding within the aquarium.

Overall, the Bali Slimer is one of the hardier Acropora species and an excellent choice for reef keepers looking to add a fast-growing SPS coral to their reef. With strong lighting, plenty of flow, and stable water parameters, it can quickly develop into an impressive colony and become a standout feature in any SPS-dominated aquarium.
