No the previous owner made the cuts, he did a really good job. I bought the tank off Ebay.
He did indeed do a great job with it
Your guy definately did a great job - looks great. However encourage you both to cut the lid, Is actually really easy with a hacksaw but you do it with a Jigsaw and you'll end up with nice straight lines like the one you got from eBay.
Thanks alphadog, i'm actually planning to give it a go. Also planning to cut a hole for the automatic feeder. At the end there will not be any lid left to cut
