Re: What is this?!?!
Possibly fungus gnats? I still don't really see what you're trying to show, just little glints of glimmering light. But fungus gnats are common viv pests which like moist conditions like you seem to have here. They're harmless but a bit pesky. Maybe try to describe what you're seeing to us; are they worms? grubs? do they jump? do they fly? how big are they?
