Hello everyone! I recently stopped by the dollar store and purchased a few fake plants. I know most people say to go with silk, but to be quite honest I didn't care at the time I was there (I was starving!) so I just grabbed a few things that looked neat and went to eat. After my low blood sugar rage had subsided I took a look at the new plants. I noticed that a few of them had missing plant extensions (Thanks China), there by leaving the metal exposed on a few points. I'm under the impression that this will eventually rust and not be good for my fish. Would adding a bead of silicone sealant to the end of each of these points suffice?
