Achilles and Mimic?

[Breakthecycle2]

Are these two fish to similar to add to a 200?

Typically, Acanthurus don't like fish of the same genus; but I bet you could get away with it if they were both small and you introduced them into the DT at the same time.

Thats what I was thinking...however, I already have the mimic in the DT.
