So I purchased a 30" FishNeedIt fixture 6 months ago for my 20 long. I have upgraded to a JBJ 30 gallon rimless which is 24". So I don't want to just toss out a 6 month old fixture, I also don't want the fixture to overhang the tank a ton. So I want to cut the ends of the fixture to shorten it. The body is made of aluminum. What can I use to cut it and are there any tips you can give me on how to cut aluminum? Thank you for any help!
