Can these be layered and used to hold up a fish tank? Or will they compress/breakdown from the weight?

I think they would be too flimsy and light to bear the weight of a fish tank full of water. There are a lot of airholes in these sheets. You would need a denser type of polystyrene foam for your purpose.

Can these be cut to a custom size by the seller?

I bought this product for my railway layout. For a hillside effect. I was able to cut it, to the right sizes I needed for my layout.Very easy to cut.

What are the products fire safety details? Is it fire resistant?

Hi there,,These sheets adhere to current building regulations.

Could I use this to insulate heat from a reptile heat mat so that the heat is projected into the habitat?

it depends if you want just insulation then yes, however, if you are looking to reflect heat into the habitat I would recommend something like a space blanket like this https://www.amazon.co.uk/Am-Tech-Emergency-Blanket-2-Pieces/dp/B005CRVKXW/ref=sr_1_2?ie=UTF8&qid=1513782943&sr=8-2&keywords=space+blankets
