I know this sounds dumb, but can you put ANYTHING in these kits? I love the look of them, but I'm not about to torture a poor fish in there.
So can you put anything in them? Like live aquatic plants, or and individual shrimp or snail? Or maybe convert them into homes for bamboo or Marimo balls? Or are the pretty much worthless?
I would like to decorate my desk with one, so I'm curious about what you all think! Thanks in advance! :)
Here's a link if you don't know what I'm talking about
