What corals can be go w/this lighting

[Lecithin]

I have a Nova Extreme 36" 78Watt lighting fixture on my 50g tank (36x19x19)

It has a 39 Watt 460nm Actinic T5HO lamp and a
39 Watt 10k T5HO lamp.

What type of corals can I put in there when the time comes? I don't want a reef tank, maybe just a few corals to accent the tank nicely.

Is this a retro fit kit? Are you sure there are only 2 bulbs in that fixture?

78 watts over 36" won't allow for much. You need to look at some low light corals like Sun Polyps (Tubastrea aurea)or cauliflower coral, etc which require direct feeding, or some low light mushrooms, etc.
