Please help me with cracking tank

I'd be wary of cutting it with a dremel. While I believe they do have a diamond cutting wheel that should do the trick, it will send tiny glass dust everywhere and would be impossible to clean out of your vivarium without gutting it, and if you're going to gut it you might as well just take the broken glass clean off.

I think she may mean cutting the plastic rim with a dremel. As far as i know, there aren't any glass cutting tools for 1/8" chuck die grinders. At least not in any of my "big name" tool catalogs.

Dremel 545 Diamond Wheel - Amazon.com it's made for hard materials. They don't list glass as a use, but you can find people on the web that have used it with success. It would be a long, labourous, and messy process here.

Cutting the plastic with a dremel to get at the glass would be fine though.

Oh, you meant those wheels. I know them, they are for cutting ceramic tile. Probably why i didn't think of it. I would never use it on glass. I know some people do, but like you said, it would be a mess. Ugh!!!
