I've been working through the first year of my 120 and slowly building out my stocking list. I tried to follow a more utilitarian fish stocking process, BRS did a good video on it back in the day. I would say I love the looks of my Yellow Tang but he doesn't eat much of my rock algae, I wish I had grabbed a Bristletooth first. With them being more docile adding them later might cause issues, we'll see. My goal was to get the right fish from the beginning and avoid the ugly phase...it didn't work. I'm sure it didn't help getting my tangs, blenny & wrasse team along with a health clean up crew but I still hit the ugly stage with a vengeance anyway. Now that I'm starting to come out of it, I think my stocking list will be important but that first year didn't seem to make much of a difference.
