Hmmm... i looked at it. It seems like it acts essentialy like a tang, swimming around the tank and occasionally picking at rocks. Something about them just strikes me as kinda boring. thanks for the input though! EDIT: i'm talking about the foxface
Depending on the size of the eel and lion, the Colored Anglers are a good predatory fish as well. Just keep in mind that they do not like to hunt for their for, they like having their food come to them. You could also go for another type of Lion such as a Radiata ( red bars with white fins). This will add some color to the tank as well as some action during feeding time.
