Ideas for adding corals to my 12g nano

[glb]

I have plenty of rock space in my nano and want some ideas for adding new corals. Currently I have zoas, gsp's, Florida ricordea and acans. I have cf light and not enough experience to consider sps but want to add softies or lps. Any ideas??? Tank has been up for three years, started with coral 3-4 months ago and it is very stable. Thanks everyone!
