Aquarium themes

I have a 55-57 gallon aquarium and want to do a theme inside it. I was thinking a miniature football field using some sort of plastic turf. I have searched for hours and cannot find any resources on here or the web for ideas or places that might sell fish friendly decorations for something like this. The attached picture is the only photo I can even find close to what I'm picturing in my head. But soccer isn't my thing.
My second idea was a nascar type theme. Is there a product or solution to paint or coat DIY decorations that seals them to make them safe inside an aquarium? I haven't started yet so I am at the perfect stage for any suggestions or recommendations. Thanks in advance. I have enjoyed learning tons of stuff in this group today. It really is a ton of good information here!

 

That's awesome very unique

 

I've seen a couple Lego harry potter themed tanks (I've read Lego is safe if you want to build something, but double check that), but if you do make anything I'd make sure the scene has a bit of height (taller ornaments).

 

I'm really interested in what options are out there as far as resins or polymers that are safe for aquariums. I can easily make the goal posts and a few other things myself out of pvc pipe, paint them, and then cover them is a safe resin. Then take a photo I have or look for one that would emulate a crowd looking on and have a background custom made. I really thought there would be more pictures on the web of something like this. But all I have found is a team helmet sitting on the floor of he tank and such as that. I think it would turn out awesome!

 

I'm surprised at the low comments. I would think there are tons of themed tanks out there.

 

I want to get a 10G aquarium that is 20 inches long 10.1 inches wide and 12.8 inches high. I would like either a pirate/shipwreck theme or maybe a zen theme does anybody have any ideas of ornaments I can get to achieve these themes? It will be home to a betta, some snails and maybe something else.

 

I would definitely go with a Zen theme over a shipwreck only for cause iv done shipwrecks now I'm all natural there is so many different natural themes I suggest picking your stock and work you theme around them

Couple of simple Zen themes for smaller tank there's a million ways to go

 

I'm mostly natural to and I'm pretty sure the fish like it better too
If you want a betta I'd get an anubias bettas like to rest on the leaves

Zen does look a little more natural

 

I would go with the Zen theme, you want your fish to be the star, not the decorations. I like this bridge

 

Google zen tanks. I have seen some really amazing set ups. They were really simple and natural with lots of plants.
