Bali Green Slimer Acropora: The Fast-Growing SPS
The Bali Green Slimer Acropora (Acropora yongei) is one of the most popular and iconic Small Polyp Stony (SPS) corals in the reef aquarium hobby. Prized for its exceptionally fast growth rate and striking, consistent coloration, this coral grows in a dense, branching or staghorn morphology. It is a highly valued coral, as it is one of the easiest Acropora species to frag and propagate.
The Green Slimer is characterized by its vibrant neon green color across its body and polyps, and it often has purple or blue growth tips when thriving under intense light. Its name “Slimer” comes from the copious amounts of mucus it produces when stressed or handled, a defense mechanism common among Acropora species. This coral demands expert care, including high water quality, strong lighting, and stable flow conditions.

Julia Sanderson –
The Bali Green Slimer has grown rapidly in my 120-gallon tank. The color is vibrant and consistent, with purple tips showing under strong lighting. I’ve fragged it twice and both pieces are thriving. Only needed to adjust flow slightly to prevent mucus buildup.
Dominic Cameron –
Great growth rate and coloration. I kept it in a high-light setup with stable parameters. It produces a lot of mucus when first handled, but it settles in quickly. Needs careful placement to avoid shadowing.
Rachel Ball –
One of the easiest Acropora to propagate. I fragmented it and now have two healthy colonies. The neon green color is stunning and it fills the tank well with its branching form.
Nathan Mitchell –
It grows fast, but I had issues with mucus during initial setup. After adjusting water flow and light intensity, it stabilized. Not for beginners without proper experience in reef systems.
