no acropora will live under that lighting. brain coral should though. acropora is a very high light coral.
btw, i still haven't forgotten about the starfish. i've been renovating a house i just bough though, and don't have much time these days. i'll hook you up after i get all settled in, if you are still interested.
bmw, i wouldn't put a fixture on the glass because if the glass broke due to heat, and water splashing underneath, the fixture might fall in the water.
