I have one for a 29g myself, and honestly i think you'll be fine unless the finish gets scratched up, and the scratched areas become wet over a long period of time since it's steel. It has a pretty good finish on it, no problems so far. I have a 15g on the bottom shelf too.
I'm not into the image, but into the hobby...
