I let it grow pretty wild, it can get ugly, but parts are pretty cool as well. Now that it's quite grown over with coralline, I feel better about leaving it be. I have two Mandarin Dragonets in the system and as mentioned in previous posts, a well matured glass pane supplies plenty of extra food for these guys. I also have an extra little acrylic fuge just below the surface, hanging off the rim of the tank to protect & encourage the pod population. I don't even mind some hair algae on the back glass, I figure if it's there, it's less likely to establish on my rockwork, plus it takes up nitrates and I export it from time to time.
