Low light SPS?

[candelloro]

I’m considering keeping one sps of some sort in my 2.5 G reef. However the light is 6W. My other corals are doing fine but would there be any sps that could survive 6W lighting? I have good water flow as well

Montipora digitata you can try.
Acropora is too difficult for your tank.
Not just because your light, but also your water parameters stability.
