I'd say no. Only beacuse you are giveing the fish the bare minimum in area to live and since this fish is easily scared it will be stressed and likely to become sick.
I would have to say no too Tin. I wanted one really bad until I read that they do best with a super deep sand bed, and not the fine grain stuff either. I've read anywhere from 6-8" is what they require.
My pearly jaw does just fine with a 2 inch sandbed. He also never leaves his little home he's made other than to eat. Before upgrading to a 27, I had him in a 14 and he was fine. Imo these fish don't need much room at all, you may get by with an 8.
Is this the same tank where you have a pair of clowns and a royal gramma? If so, no way. You should really keep only one small fish in a 8 gallon tank.
