stainless steal or deck wood are both treated with chemicals,hummmmm lets see now chemicals and fish, do they mix well---------------NO!

Will it smoke for long enough that you get a chance to notice, before it bursts into flames?

you can always go to an electrical supplyer and get the tubes that go over the lights so they are water tight then
