In regards to placement in tank: You'd benefit from a mid-level placement, but I would start it out low in the tank so it acclimates to the light properly. Keep away from other corals: it'll sting the tar outta them. I'd be most concerned about this aspect of keeping that coral, as when it takes off, it will start encrusting everything in the surrounding area.
In regards to lighting: You should do fine with the lighting type that you are currently supplying
In regards to flow: Your flow shouldn't be direct, but you'd probably get good results from moderately strong water movement around the animal.
Feeding: You could probably spot feed and see some accelerated growth. Some people feed with pellets or meatier frozen foods such as mysis or krill. I personally cut flow to the return and circulation pumps when feeding my LPS.
Just my 2 cents. It's a relatively hardy animal as long as your parameters are stable.
Hope this helps. I'm sorry nobody responded to your posts sooner!
