Here's our occelated morey (27" maximum) and although somewhat piscevorious, doesn't bother any of his tank mates (it IS a large tank though, 300 gals)...in the pic, he's eating a 5" shrimp.
His name is "Hannibal", by the way, as he was locally captured and bit half-way through my finger in the process.
He was also eating less than 1/2 hour after being introduced to the tank.
