I'm thinking about setting up a sw tank.

I've always been a fan of the 'shimmer" look, so I would love to have metal halides. However, I'm not a fan of the rimless look, so I'd want a canopy to match the stand.

Is it possible to have MH attached to the inside of the canopy of a tank, so that you don't have to hang the lights from a ceilling?

I understand MH get really hot, so you need to have them x amount away from the water, but are there tanks out ther that have the MH in the canopy? Is it reasonable to do this?

It would be an SPS / acro dominated tank.
