Those are tubifex worms, also known as sludge worms! They can indicate poor water quality when found in large numbers in the wild, as they are highly tolerant of pollution which kills off their competition and allows them to proliferate and take advantage of the excess nutrients which are often the cause of the water quality issues. However, I don’t think that *inherently* means the water quality is poor when they are reproducing in an ecojar – by nature they have limited competition or threats in such a small space, and they are just a hardy enough creature that they’re less likely than a lot of other critters to be killed by the shock of the condition change when taken from the wild and put in a small, low oxygen environment.

Boogie worms. Harmless detritivores and very common in ecospheres.
