I too started with some nice resin decor. While they looked great for a few weeks, the silk plants fell apart, and the paint came off pretty easily the first time you clean the thing.
Also, I am pretty sure that I lost one of my cory's in there. I removed an item (a resin log, which i replaced with a real one) the stuff that came out of it when washing, I think was that Cory.
I have been slowly changing those aritfacts out, as I am able to replace em with nice Rootwood.
