Golden Stripped Maroon.
I used to have one percula and one GSM, did not last long, the GSM what beating the living hell out of the percula, so the GSM went back to the LFS for credit.
I have a Maroon clown & 2 false perculas in my 90 gal...the maroon occasionally chases the perculas but not that often...they pretty much stay on opposite sides of the tank. The perculas will venture to the other side and vice versa but usually there is not any chasing.
Wouldn't reccomend it, as the GSM will eventually become larger than the percs, and they are more aggressive to begin with, especially against other clown species.
