I've got one planned out already. A 8' tank with a shallow coral reef section that's 4' x 2' x 12" connected to a deeper drop off that's 4' x 2'x 2.5'. The custom 1" glass I'd need would probably cost a good fortune but I think it'd be worth it.
Right now I'm focusing on saving for a nano reef though lol.
My entire basement filled with 50,000+ gallons with pirahana that i could hand feed from my mouth with a chainmail suit on, id also throw in officials that hold me back business wise, but that the future project for now stickin to a concrete and fiberglass under 5000 gallons i can pet my pleco in lol
I would love to have a house build under a salt water! (basically a huge pong on a piece of land) and most of my home will be made of glass for viewing!! And saltwater ofc!! imagine waking up to all these glorious wildlife! Ahhh
