I've started another experiment with closed ecosystem in a jar. Three weeks in, it appears stable, I have some greenery, lovely snails - most hatched already within the jar, a hydra, a very active black speck I am unable to identify or photograph, small worms, and some tiny crustacean friends (copepods, daphnia, ostracods)...

I am surprised how happy it makes me to just watch those little guys go about their business.
