Excuse me if this is in the wrong place as this is my first post, but I am hoping to experiment with my Fluval 13.5. I have previously had multiple colonies of zoanthids, an alveopora, a goniopora, mushrooms and several other things throughout the tanks previous life. The only real goals I have for this tank is to be able to have an anemone of some kind, and a GSP wall on the plastic false wall. Other than that I'm open for almost all suggestions. If you have any ideas please, tell me! I really want to have fun and challenge myself with this tank.
