I saw a photo of a really beautiful fish, a springer's damsel, and have been trying to find some more information on it.
As I have an anemone (which is frustratingly massive) I can't take the puffer fish route, and I am quite hestiant about getting a boxfish as I am fairly new to the reefing scene and I heard they are quite easy to stress.
Here is a pic of the kind of damsel that caught my eye.
