By junior high I became a natural tank snob, wanted to have a tank that looked like a natural setting, got rid of the dyed quartz gravel in favor of natural, stopped keeping fancy varieties and only kept wild type fish, then got into biotope aquariums and only kept fish that would be found together in nature.
Then I married a single mom of a 5 yo boy. My stepson liked my aquarium, was always wanting me to buy fish he thought were cool that didn't belong in an african rift valley cichlid aquarium, so I got him his own 10 gallon for his birthday. For some reason I felt his red wag swordtails would be happier fish with a shipwreck like Davy_Jones posted. What's most important is that my stepson loves his tank, loves to fall asleep with the light on so he can watch the fish, and the shipwreck reminds him of his favorite movies, Pirates of the Caribbean, but I have to admit I enjoy looking into it, enjoy the crazy world of whimsey it creates, the corydoras catfish snuffling around it like a nurse shark, the rainbowfish like tunas.
He's in 3rd grade now, so maybe in a few years will want something more natural, maybe I can nudge him to do an indopacific brackish setup, my second-favorite setup, but for now I dig the shipwreck.
