OMG- How ironic- I just finished reading the RC TOTM winner article and he mentions NOT getting Foxface cause as they mature they eat coral.
I would have otherwise agreed with most here since I have only had one, never touched my corals, and only got rid of it cause it, got too big, AND was always "freaked out". Anything scared him and he darted back and forth. I felt he scared everyone else, so i caught him and traded.
Here is the link to the TOTM:
