You are certainly well versed in fish and their habits, Vincent. Most people usually excel in anything they enjoy/are interested in, so you are obviously one of them.
As I said (basically), I do think your idea is very good, but I have decided to just stick to the common humidity tray for now. Sometime in the future, though, I know I would enjoy taking care of unusual fish and plants, so that is an option for probably later.
Thank you for your reply and interesting info...and to answer your question, yes your input helps.
