That's a conundrum. 80 degree gives you good spread, but sacrifices par. 60 degrees will force you to raise the light off the surface at least 24 inches. Just depends on the look you are going for. I would choose one and buy extra optics in case it doesnt look right. From what I understand they are easy to change out.

Depends on the depth of the tank, but probably. I would pick up the extra optics just in case.
