Cynaria would be very happy there but may outgrow that spot I find they thrive with low flow and light but actually need to eat unlike alot of coral they waste away without feeding
i would put a nice acan bowerbanki or rainbow chalice in that area if you find any. there are a lot of options though favia, cynaria, scoly, blastos, any soft coral (but i think softies will quickly out grow it) etc
