what parasite did I find

[texron]

I believe that it's not a parasite, I think that it was mosquito larvae.
It fits the descrition that you gave and I can not think of another organism that swims with a "jerky" motion. Use a search engine for pics to double check.

The pictures I found on Google don't look like what I threw away, but the pictures I found were blown up about 5-6 times normal so It's hard to be sure.

i have never seen white mosquito larve

do they look like these http://www.ball-pythons.net/forums/s...55&postcount=2

No, MUCH smaller. What I found look more like tadpoles than worms. maybe 1/8" long

What type of substrate do you use in the enclosure?
