Been giving some thought to this lately, as I'm considering a new tank set-up that will be almost exclusively zoas rather than a mixed reef. My tank will be small (a 20gal long), but I thought it might be nice to generate a list that others may reference as well. In thinking about the fish, I'm wondering if anyone has any thoughts of or experiences to share regarding fish that are must haves (help the Zs-n-Ps out in some manner) or definite do not want (harmful to Zs-n-Ps) in some manner.
Based on my own past experiences, I'll be excluding all types of tangs (size considerations as well as the fact that they often turn to nipping polyps) and angels (again size considerations as well as potential nipping). Due to size and sandbed considerations, I'll also be excluding Diamond Watchman gobies as well. Beyond that I'm not real sure, so I'm open to some suggestions.
Thanks in advance for contributing.
