What Are The Tiny "worms" In My Neon Tank?

[varial]

Hey everybody, I've been soaking everything up on this forum for a while now (there's some very smart people here), and have a question. I was looking at my Neons today, and saw tiny little worms (for lack of a better term) swimming on the surface of the water. They are thinner than sewing thread, and about 1/2" long. They look cream or maybe even clear in color, it's hard to tell they're so small. I immediately took my neons out to a spare tank, because I'm not sure what these are. Any ideas???

The setup was 6 Neons in a 2.5 gallon tank with a few ramshorn snails. Thanks for reading!

That tank is way to small for neon tetra's they are shoaling fish and need room to move.
All about that tank size is good for is a betta
How long has the tank been set up, and stats would be good in ammonia,nitrite,nitrate,and ph.
These type of worms are due to over feeding, lack of maintance, and a ammonia reading.
