Best light Bulb to show for oscars?

[chrisstylez1]

Hey guys,
I received a used lamp fixture for my 75g tank, it has 2 coralife 20,000k high intensity purified super day light 40 watt bulbs in it, and i was wondering if this is the best bulb for oscars or would you recomend another 1?

if you like the look, it should be good. 20000K bulbs are whiteish blue. so it should look pretty good to hightlight the reds of the oscar..

I like Hagen Powerglo bulbs that are similar at 18,000K (white with a hint of blue)
