I went to Princess Auto today in search of aquascaping tools. They were having a sale. :)
I got a three pack of stainless steel tweezers, I believe 12", 10" and 8", for the lovely price of $2.99, regular $7.99. So, if your tank is in need of a little tweak, or you need to reach something and you don't want to get too wet, you might want to head down and pick up a set. They had quite a few, mostly at the end of one of the aisles. Happy water gardening!
