20 gallon rimless ideas?

[VanDalsenReef]

So I have the opportunity to add a jbj 20 gallon rimless frag tank (24x20x8 I believe)
My questions

Will two kessil 160 be enough? Or should I put on two old 350w I have sitting around (they still work fantastic)

What are some "utility " fish I could add for pest control? I don't really do nano fish and don't plan on having sand or even rock unless its needed for the fish to hide in.

20G is a bit small for most utility fish. The only ones I can think of, and some of these are still pushing the limits, are:

Court jester goby/rainfords goby for algae.

Neon goby for parasites,

6line wrasse for other pest worms and critters.
