I got one of those little 8oz blue water bottles with aquarium clip from Wal Mart. I think there made by First Nature or something. Well where the instructions are (on the back) it says how to put water in the bottle and how to screw the lid on, but nothing about how to clip it to the aquarium? Theres a long black thing that looks like the water bottle goes against and one of those round metal clip things, but I’d really, really like to know is how do you put in on an aquarium? Show me with some pics. I’m trying to put this thing on a 10gal aquarium. Do you need to drill thru the glass? Any info would be appreciated!
