Can manufacturers coat aquariums ?

[Backreefing]

I’m referring to glass aquariums . But can manufacturers coat the inside or maybe outside surface to be mirrored? The results would certainly intensify light inside the aquarium. Emagine if the glass sides reflected 100% of the light back at the corals . But we would need to see in , it is unessary for the corals and fish to see out. IDK unless you’re training the fish to respond to you
What are peps opinions?

You could definitely mirror coat the glass, there is even spray paints now that can make a mirror finish on glass. Most of my tabks have very little light hitting the glass though but perhaps it would be good for a frag tank?
