It is just fish poo. My guppies have the red poo sometimes.

It could be poo but colour would depend on what you feed them.  Are these red things lines on their fins?  How many guppies and what size of tank?  Is it cycled and is there anyone else in it?

It sounds like Camallanus Nematode, an intestinal parasite that spreads to other tank mates.
