I wouldn't do a Urau with a Pearsi either. Although gentle, Pearsi would pick on the Urau. I love my Pearsi. He is the most personable fish I own and really looks farward to seeing me at feeding time. I tend to play games with him on the glass. My Bocourti is every bit as big as my Pearsi and I've actually heard the Bocourt get bigger. I would do the Pearsi for sure If I were you.
