My cory's are taking over

[WGC-Katana]

So I did an awsome gravel vac today, took EVERYTHIG out of the tank (I have artifical plants so it's easier) and cleaned it all up. Well I decided to rearrange things. The problem is my clown pl*co used to sit out in hit log and he was a happy fish. Well since the rearrangement it seems my 5 elgans cories have taken up residence in his log. Should I be concerned? Should I find another log type thing for my Pl*co?

It's always a good idea to have more than one cave/log when you have bottom feeders. I would say get another log or some driftwood that has a hole in it.
