Help with picking a coral

[ponokareefer]

I've got a few spots in my tank where there is high light(5 inches from a 150MH, I know, not the highest), and is about 6 inches from a Koralia 3 powerhead. I've tried putting acans there, but they are showing signs of burning from the light. There is too much flow for frogspawns/torch's/hammer's, as the ones I have put there close up. It is on a slope, so I can't "glue" a clam there, or I would, as this seems like ideal conditions for them. I really want to avoid SPS due to the near perfect water quality required, and high demand on calcium. What other choices do I have?
