Just thought I would share this in the plant forum since it's directly related to plants (instead of the DIY). My fish tend to kill my plants so I decided to "contain" the plants. I used a plastic iced tea holder from the Chinese Food Store (lol) and made holes in it for water circulation. I placed at the edge of the top of the tank and used my lamp to hold it in place. The anacharis are thriving in it so far. I'm sure there's a fancier way to do this but I thought I would share.
btw that's my thermometer hanging from the plastic container lol
