Fish and Acans Questions

I have a 100 gallon tank that I am thinking of turning to an Acan dominant reef. The fish currently in the tank may or may not be OK with this. My fish list is as follows:

1 Female Watanabi - Never picked on a coral
1 Goldflake Angel - Already known to be an Acan connoisseur and also seems to like Frogspawns so he will get removed. Though he has never touched Zoas, SPS or my Torch.
1 Firefish
1 Copperband Butterfly - Never picked on a coral
1 Lawnmower
2 False Percs

I was thinking of pulling the Goldflake and adding a Purple Tang but have seen stories of some developing a liking to Acans. There was also the idea of a Melanurus wrasse but it possibly taking a liking to my CUC could be an issue. Are there other ideas for fish that I can add that could suit the needs for an algae grazer and a pest eliminator?


Thank you

Greg
 
I have a lot of tangs and a flame angel in with my acans. Looking at trying my luck on butterflies.
