flow-moderate to strong
light- I would say moderate-Favia species if often found at depth of 25 to 30 feet and is therefore not accustomed to high intensity lighting but, rather, to lots of blue. When first placing such a coral in your tank it is prudent to shield it somewhat from too strong lighting (this is especially the case if you are using metal halide lights or several VHO type bulbs). Once the coral acclimates though, it can gradually be exposed to more lighting.
It is a filter feeder
also sense it is around 5" it would go for around $50
