reef tank over top of fire place

[e46er]

I'm a gas fitter...... Fireplaces don't come with tempered glass that's a sperate pane if glass generally very expensive which is what you see when fireplaces are in ensuites close to water
regular glass that's hot water splashes on it crack shatter all bad.
It would look cool but not practical at all I'm sure you could find a much better spot to put a tank
