All those so-called "tacky" tank set-ups are not at all tacky, as far as I'm concerned - they just appeal to different types of people and I think there is too much snobbery in fishkeeping these days.
What's wrong with making a tank look fun if that's what you're into? What's wrong with a bit of Spongebob if you're a fan of Spongebob, regardless of age? Or pirate ships if you're a fan of that sort of thing? I'm certain the fish don't mind LOL
Why refer to them as "tacky", I don't understand... makes it appear that there's something wrong with it - and there's not!
The style of tank we set up is just a reflection of our inner personality (or those of our children, grandkiddies etc) and I think it's unfair to belittle them and make owners of those tanks feel inferior and that they are not "proper" tanks and that there is embarrassment in owning such things.
Some people have a wacky sense of humour, or are into colour-scheming everything in the room - so what? Good for them, I say - not to feel like they need to conform to the "naturalistic" point of views. After all, there's nothing natural about keeping fish in a glass tank, no matter how many plants you shove in there.
So all of you out there who have purple gravel, pink plants, skulls, mermaids, boats, ruins, glow-in-the-dark stones etc - applaud yourselves for staying true to who you are and what you enjoy rather than just following the crowd because you feel you have to.
Beauty is in the eye of the beholder, as the saying goes...
