I got a 5" rainbow shark for my 55g tank yesterday. He seems to be aggressive with my cories, is this to be expected? I am considering moving my 3 corries to my 29g tank.

I have a "pile" of drift wood in the center of the tank; the corries liked being around that area however the rainbow shark likes being in that area too. The shark will now chase any cory that comes close to the pile of drift wood. I am surprised to see that the shark does not pay any attention to my 2" clown pleco at all....

Should I move my cories? I do see some minor damage to one of their fins....
 
yeah it is expected. rainbow sharks get very aggressive as they age especially towards fish that are a similiar shape, which cories are. definately move the cories
