Fish Problems (Ich, Parasites, etc.)?

[superdanag]

I have some weird stuff in my fish tank, and I can't figure out what a lot of it is. I'm pretty sure that the fish have ich, and also there are some things on the bottom of the tank on the gravel; one of the things is that there are these weird, small, curly, white tubes. The other are these weird greenish brown log looking things there are 3 in a single area. Also, in only one area and it is very small there is this white thing that kind of looks like cotton on the gravel that I think may be some kind of fungus? Any help appreciated, I'm trying to post pictures of it too:

K so the tubes are just droppings... But what of the others? The logs don't look good to me, and I think the fish have ich...
