I like the idea of a magnetic closure for the door.

I think I'll probably go with some kind of hinged door, sounds easier than sliding doors

I got the measurements slightly wrong for the tank, it's 24" long, by 18" high by 12" wide. Therefore I'm thinking of making the side of the tank the front and have a side opening door, to make more viewing space. Also then the door doesn't have to be glass as it will be just a side wall and access point, if you get what I mean.

This is all just by the by as I'm now using the tank as a nusery tank for my youngest axolotl, he/she was growing out of the tub I had him in!

Also, I'm moving house in the next couple of weeks, so all projects on the back burner for now.
