So I got this 55 gallon bow front tank for practically nothing. I tried those carpet lining things that Pet Smart sells but it's not working out so great. I love the way the slate tile looks in everyones vivs and my guys nail are sharp so I would love them. Is it just as easy to cut an arc in slate as it would be to cut a straight line? Is there a Dremel attachment I can do this with because I pretty sure Lowes isn't going to help with that custom of a job. Thanks!
