What corals to put here?

[codydemmel4]

So my tank is SPS dominant, but I have a big bare spot in the front because of my powerheads meeting in the middle and push down hard. So I need some suggestions on what to put in this bare spot. Needs to not need a ton of light since it's at the bottom of a 24 inch tank and needs to be able to withstand a good amount of flow.

Was thinking of placing some real small rocks and having some clams down there but looking for suggestions.

Purple bonsai acro?
acans?

Green Star Polyps and let them attach to the glass/grow and cover so it looks like grass growing. Just keep them trimmed to that area

Sympodium is another option. These tend to grow much sower than GSP and are not as invasive.
