Water parameters: Nitrate 5-20 mg/l, Phosphate 0,05-0,15 mg/l
Feeding: They are adept feeders that can grab and consume a wide variety of foods ranging from coral-formulated sinking pellets to frozen food such as brine shrimp, mysis, and krill.
Acanthastrea are found around the islands of the Indopacific including Fiji, Tonga, Solomon Islands, and the Great Barrier Reef. Our Acanthastrea typically come from Australia.
Acanthastrea can be kept under a variety of light conditions ranging from dim to medium-high lighting. Here we have them under very low light T5 bulbs and relatively low light LED's. It is important to note that these LPS change color dramatically depending on the light they are provided. Despite the change in appearance from light, it does not appear to affect the health of the coral, just the aesthetics.
We recommend keeping the coral in a low to medium flow area of the reef display. Too much flow could cause this particular species to become stressed and not extend fully. Lower flow also provides more opportunities for feeding which we feel is an important part of keeping Acans healthy.
Acanthastrea in our opinion must be fed for long-term health. There are a variety of frozen fish foods available that make outstanding meals for Acans. We like to feed a mixture of meaty foods such as shrimp, fish, and squid with vitamin additives and highly unsaturated fatty acids (HUFA). Our Acans almost always have their feeding tentacles out (even during the daytime), which we view is a sign of good health.
IÕve been feeding them primarily frozen shrimp, both krill and mysis for some time but recently IÕve been trying some powdered plankton foods. ItÕs hard to pay attention to every coralÕs feeding habits, but I decided to shoot some time lapses of this coral eating first just frozen, then a mix of frozen and Reef Roids, and then lastly just Reef Roids. At least with these specimens it looks like they took to the powdered foods pretty well, so thatÕs something to pay attention to.
