LIGHTING
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.
Low Light
Low light translates to about 30-50 PAR
Medium Light
Medium Light is between 50-150 PAR
High Light
High Light is anything over 150 PAR
Β WATER FLOW
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.
Β FEEDING
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.
Β PROPAGATION
In terms of propagation, this genus has been successfully fragmented. If you are interested in propagating them, take a look at our Acan propagation video below. The coral in the video is a Micromussa lord, but the same sort of care applies to echinata.
A WORD OF CAUTION
It is important to note that this coral is aggressive to other Acans. They cannot be kept in contact with other types of Acanthastrea.
Β ACCLIMATION
Proper acclimation is extremely important considering the stress imposed on the animals by the shipping process.
