Acropora Yongei aka Bali Green Slimer Acro Coral is one of the fastest growing Acropora coral in the world. Its attractive neon green, coupled with its remarkable resistance and growth rate make this coral one of the most sought by acroporas for the newcomers to the SPS world. And it is a really tough and adaptable acropora, even more than some other corals considered for beginners. If irritated this species produce large quantity of Mucus or Slime. Hence it’s not so appearing name. A classic aquarium coral which has been in the hobby for more than 20 years. It has thick, neon green colored branches that produce copious amounts of slime when disturbed. Bali Slimer tends to have widely spaced branches which give the coral an amazing open shape which fish like Cardinals enjoy sheltering in. Frags vary from 1-1/2 to 2-1/2 inches. It is also important to note that our captive grown corals are cultured from corals that have been raised in captivity for at least 3 or 4 generations. This makes these harvested corals hardier than their wild cousins. Being fully encrusted, allows them to ship better with less stress when compared to fragile and newly fragmented counterparts.
This coral requires moderate to high water flow
Prefers a moderately to high light level. Alter its position in the aquarium depending on the lighting, and provide at least 3 watts per gallon. We recommend a 14-20K color spectrum for best coloration.
Can be placed in close proximity to other similar peaceful corals in the reef aquarium. Remember this coral can grow big over time so give it room to grow and branch out.
Diet and Feeding
All your SPS corals will be happier when they are fed. The mouth sizes for each polyp is relative to the body size of the polyp and this size will more or less determine the particle size a coral can eat. We have found that even the smallest of SPS polyps, even Anacropora will accept food. There are several coral foods available to the aquarium hobbyist and we generally mix up a few with varying particle sizes and target feed this to all of our corals. We've had success feeding all our corals and find our Echinophyllia (chalice corals) Montiporas, Acroporas especially A. millepora among others respond well to feeding. When you are feeding your corals you will want to turn off the flow in your tank and gently target each coral. We like to feed our corals at the end of the day when the lights are still on their daytime light setting. You can even try broadcasting some food in the tank before you target feed as a "dinner bell" for your corals, or try polyp lab reef booster as a way to prepare your corals to feed. We recommend feeding your corals several times per week. After a few days of feeding your corals should be responding quicker to your dinner bell and looking all and all more vibrant. Some of the benefits we have noticed after 2-3 week included more polyp extension, puffier body tissue, more colourful, increased growth (compared to unfed corals). Excellent SPS Cora food include Phyto Feast, Oyster Feast, Roti Feast, Phyto Plankton, Zoo Plankton, Marine Snow, Coral Frenzy, Cyclops. We also always recommend target feeding since it gets the corals fed using less food while keeping your nitrates and phosphates lower.
It is important that the proper calcium (420-440 ppm), alkalinity (8-9.5 dkh - run it 7-8 if you are carbon dosing) , and magnesium levels (1260-1350 ppm) are all maintained. Raising magnesium levels gradually up to 1400-1600 ppm is a great help in combating algae outbreaks, just keep Calcium and alkalinity levels where they should be as you raise the Magnesium level. Try to keep Nitrate levels below 10 ppm, Phosphate levels below .10 ppm. We recommend doing frequent water changes to keep Nitrate levels below 10 ppm. If Phosphate numbers are above the .10 ppm level, change your phosphate control media. To make the most efficient use of your phosphate media, we recommend the use of a media reactor.
