I suspect it is some sort of larvae. I did see one come out of the substrate, like a worm. No signs of them attacking fish or shrimp thankfully. I have been chucking them out anyway.

edit; they are nearly an inch long
 
It could be planarian worms ( flatworms ) if they are they could pose a problem - copper based treatments work but the dead bodies can pollute a tank very quickly, they reproduce fast and are cannibalistic as well as attacking small shrimps
 
I don't know much about this sort of thing but I thought maybe a fly larvae of some sort, like crane fly or similar?
 
If it's flat and moves like a ribbon through the water it's a leach. On further inspection it looks more like insect larvae. Bear in mind dragonflies are dangerous

Definitely not dragon fly
Pretty sure 99.9% it's crane fly
Back in the day I was on the Northern lecture circuit giving talks on pond life & insects.
(Not sure where my id book is at the moment though)
 
Hi all,
Pretty sure 99.9% it's crane fly
They are pretty common in fresh water, I'd always assumed that they were found only in swamps and over-grown ponds etc., but we get <"Tipula maxima"> larvae in the kick samples from the stream on campus, and from the By Brook to the east of Bath, which are both pretty clean limestone streams.

cheers Darrel
