What to put towards top?

[MidwestReefer1989]

Hello! Thank you to the individual who answered my question yesterday! I am trying to decide what I can put towards the top of my rock structure. Its about 3 inches from the top of the tank. I want something that won't spread or take over but will still be a great centerpiece.

Will the frogspawn attack the hammer coral that I have on the side. There is space now, but want to avoid future conflicts if I can.

they usually don't like each other. the hammer wouldn't be the one to worry about as it has much longer sweeper tenticals. I have mine a few inches from them with no real issues.
