Ok, I know that sounds really weird, but here is the thought that popped into my head the other day. When we moved, I had a lot of extra water bottles since we didn't bring all of our rats with us. Now that I'm starting up small colonies again, I'm taking out these water bottles one by one to wash, sanitize and use. The other day I went to get a water bottle that was sitting out and find it full of greenish water. It had been sitting partially in the sun that comes through the window and it was full of algae.

Now I know that plecos eat algae, yes? My husband has always wanted a pleco and I was thinking that when we moved into our own house, we could get one. Would it be possible to set a few of these water bottles up near a sunny window and grow algae in them for the fish? I won't be needing these water bottles soon as they are not the kind I will be using when I have my tubs and racks. (hang from a wire instead of attach to the side of a cage). It was just a really weird thought and I want to hear some people's opinions on this.
