This tiny 10 ml ecosphere is 4 years old. Water is murky cuz I moved it but that little piece of guppy grass is still green and lots of protozoa buzzing around.
For safe keeping I keep it inside a jar or tank so it won’t accidentally roll off and break. But it’s sealed and has its own little air space inside. Picture in comments.

That’s where it’s parked now.
So cool
Beautiful. Nice flex.
