i need some help on decorating my tank, any suggestions? is a 4 foot/156litres..
We usually buy big hunks of slate (you can get it in red or a grey color) and break it up. Then use aquarium silicone to make different things. We do that with reptile tanks also. I might have a picture of one of those just to give you an idea.

What we used there was a flagstone of some kind. You wouldn't want to use that in water. You'd end up with nothing in a year or so.
