I've recently upgraded to a 30 gallon and I'm finding myself with a lot of open space. I want some corals that have some good movement and some really nice colors. I was thinking a red goni but that's out of my price range.
Green sinularia, torches, gonipora, finger leathers, and xenia. I have some red pulsing xenia for free if you wanna pick in lithonia as well. Oh yeah sea fans and whips
