I was gathering some freshwater amphipods at a local pond yesterday to innoculate my tank, and ended up netting a bunch of these things...but could not figure out what they are:

Here is one as it looks in water:

Anyone have any ideas?

My vision isn't that clear with photos -- I can't even tell what shape you're referring to! Sorry

In the water photo, it's the one just above and to the right of the bright glare--you can see the pair of dark objects in it's body.

They look like glass worms. One guy brings bags of them to my fish meetings and people buy them like crazy. He nets them from ponds, and feeds them water from his turtle tank. He says they are filter feeders? . I have gotten them from him for feeding small fish. Good stuff.

Yup, they are glass worms. They are predatory on small things like Daphnia---no harm to your fish, unless you have fry. The first time I used them for fish food, they were so transparent, that the fish, one by one, had to discover them. You could tell the fish who had discovered them from the ones who had not by the increased size of their bellies
