I have these 18mm glass balls that I would love to make into tiny ecosphere. I did a few experiments with moss lat month but anything I put in it seems to rot/melt away.
Does anyone have suggestions on what I can put in here that would survive well? It can be anything for a closed ecosphere or a water ecosphere. Thanks!

No.
But if you’re obsessed with something tiny and living, air plants can make it in something small and hanging/exposed
Maybe algae, I doubt any actual plants could live in there.
a single strand of thread moss
You should put a stopper in it or put plastic wrap on it just enough to cover the whole. That should hold moisture in it. Or if you already tried that and it didn’t work then maybe you need less moisture and so don’t use a cap. People buy Venus fly traps and they die because they just put them in the window in the open air and they dry out and die. I know you can’t fit those in there, just saying it might be a humidity issue. That’s a really cool idea and I hope you figure it out. If you live close to some wood, just go searching for something small that you like.
Water for a river, creak or lake and algae
Maybe duckweed? If you do use duckweed though, make sure you’re careful to not shake it around too much, as leaves could die if they become submerged. That being the case, don’t fill the ball any higher than halfway if you’re gonna put duckweed in it. If you’re going for a terrestrial build, maybe moss. Aquatic moss might do fine for an aquatic build too. At least those are the only ones I’d recommend as far as true plants are concerned.

Like this? It’s over a year old and has a pinch of guppy grass in it along with pebbles and water from a pond.
I think the reason mine has lasted so long is because it’s sealed and actually lives within another aquatic ecosphere, under water. So it rarely gets moved and has always the same temp and light.
The first issue is temperature stability. Anything you put in there will need to be worn around the next 24/7 and put on a regulated heating pad overnight while you sleep.
The temperature swing from 30c to 20c that happens in about 5 minutes after taking off your chest is enough to stress and kill any animals over time.
You will need it sealed airtight, so it doesn’t lose water and become a cesspool of chemicals through top ups.
A brine shrimp and deadwood from the pond are about all you have a chance of keeping.
Good luck! It’s an investment of your every second to just keep these alive
