Green Bali Slimer

SPS Deep Dive – Green Bali Slimer

When I was first getting into this hobby and checking out mature reefs at my local fish tank stores I fell in love with staghorn corals. Fish swam through the branches and they just looked like a natural part of a reef you would see in the wild. One stag that caught my attention was the Acropora Yongei or “Green Bali Slimer”. This coral is an eye catcher given its vivid green color and wide, spidering branches. As the name suggests, they do “slime” when touched or disturbed so it is wise to minimize contact.

The Green Bali Slimer is one of the more hardy SPS corals so it is a good one for folks to try who are just getting into SPS. I would recommend giving it a go after success is achieved with less demanding SPS such as Birdsnest corals or Montiporas.

Green Bali Slimers Need Room to Grow

Slimers are fast growers once they are established in a tank so they should be given a lot of real estate to grow. I had one in my 225 gallon tank and it essentially took over the whole left corner of my tank, touching and encroaching on other corals. It grew so fast that the tips started to spread at the top in the shape of a V in an attempt to find more space to grow. They actually seemed to be growing out of the water!!! Anyway, it really pained me when I had to get rid of it but it was just way more aggressive than its neighbors.

Green Bali Slimers Can Get Large, Fast!

In my experience this coral does not need a ton of light or flow to thrive so it can do very well with moderate lighting and flow. However, it should be noted that the color of the coral can vary from a yellowish green to a deeper green or even a neon green depending on the intensity of light. So give this coral a shot if you want to add a splash of color to your reef. Just be mindful of how fast it grows. You might have a bunch off small colonies rather than frags to swap with fellow reefers in no time!
