Strange worms in vivarium

[Sugar]

Hi

A few days ago I noticed a patch of white lively worms in the water in one of my vivariums. Does anyone have any idea how I can find out what they are? It's very disconcerting.

Thanks

I had something like that on the glass of my vivarium. I took to the vet and he said a type of slug.
