Aussie Lords in general prefer minimal lighting at around 150 par and low to medium alternating flow. I would also recommend target feeding a very small amount once a week with a good quality meaty frozen food, but just make sure their feeding tentacles are out, as it not it will roll right off the coral and end up somewhere you usually don't want it (like under your rock structure, where it will rot and possibly mess up your water parameters).

Lighting = Low Light at around 100 to 150 par
Flow = Low to Medium Alternating Flow
Feeding = Good Quality Frozen LPS Food 1x / weekly
