You have just given me an idea. I allways wanted to have a fish tank at work, but I have no access to any power plugs where I sit. Our desks are quite small as well, but we are sitting in round pods with a raised middle area. I could easily put a fish bowl up there (would make water changes easier as well). Can I keep a Fishbowl with no artificial light (we are near a window) ? Would an Anubia or Java Fern Grow in there ?
