Heard that as well, they are the most mild-mannered of all dottybacks, but can still be quite aggressive. My purple firefish quite big and was first to be added to the tank. Don't know whether I should risk it and add an orchid dotty.
Yup. I'm looking for Half and Half. (C. dimidiata or C. iomelas). Got 2 species but they look the same to me, I just want the nice halfway black and white pattern. Anyone know where to buy?
