I used a red 12 volt dc submersible light strip under a fuge full of chato for a bit. Didn't want any overhanging lights,, looked cool whole fuge just glowed red chato got super thick . It was about 25 ft long so just zip tied it into coils and tossed on bottom of tank. Came off a floating dock that was under lit..I’ve been following along too.
Makes me wonder about what else we could do with lighting.
Upside down fish? Floating reefs look cool over sand just not many places for the fish to chill
