A couple of CWD questions...

[froggsong]

Okay, first, for the past couple of days my CWD's poops (I feel so silly typing that) have been a different color than they normally are. They are normally brown, and now they are MUCH lighter in color, almost white. Am I dusting his crickets too often? Could he be getting too much calcium and it is changing the color of his waste? I know that happens if dogs eat too many bones.

Second, I had a dish of cricket feed in the tank under his pond where the baby crickets hang out (and the bigger ones that escape his mouth) and the filter fell over and poured some water underneath the pond and wet the feed. When I found it last night, there were tiny white worms in it. I immediately took it out and threw it away, but I am worried about what the worms were and how they got in the cage. Should I worry that they may be some type of parasite? Or can a parasitic worm live outside of a host? Are they a normal thing that gets into a vive? I've never seen them before, and they were just in the dish, as far as I could tell, but I am worried that they could potentially harm my dragon. Something in the cricket feed smelled like it was fermenting, and that's the area they were in in the dish. I bought everything I need to redo the cage yesterday before I found the worms, but I was planning to construct it outside of the tank and then drop it in so I don't have to find something else to keep him in for a week or so. I want to be able to have him out of the cage for as little time as possible. Should I remove him from the tank and change the substrate?

I did a bit of research just now before I posted the thread, and these look very much like white worms (also called pot worms, I think?) that people generally feed to fish. I got the dish out of the yard (where I threw it last night when I was freaking out about it a little) and took a picture of the few that were left inside of it:


The toothpick is in the picture for a size reference and was the only thing I had on hand.

The worms seem to die quickly if they get dry. I hope that they are just those worms that people culture for fish and small herps. What do you guys think?

This is a website that has pictures of the worms that are fed to fish:

Scroll down til you get to the picture of white worms. As far as I can tell, this is exactly what they looked like lsat night. The ones in the picture I posted were getting dry and soon died after I put them on the paper.
