What are suitable corals for this setup?

[Beverly]

I have two 5 gal tanks, 10" high. I have placed the tanks side by side and have a 3' NO fixture with two 30w 5500k tubes over them.

Currently have them filled with untreated tapwater, a small powerhead, heater and thermometer. Tomorrow, am going to test temp rise with the light fixture directly on top of the tanks' glass. Kinda think temps will rise quite rapidly with all that light on such small tanks. I can raise the fixture to keep tank temps more stable, if required.

If I can manage to keep tank temps stable, I plan to put at least 2" of aragonite sandbed, some LR, no fish, maybe no mobile inverts except snails (but we'll see), and want to have corals of some type. With that amount of light in such shallow tanks, can I have sps corals and/or clams, or am I restricted to lps and softies?

TIA for your thoughtful suggestions.
