I just got home and my male guppy has an orangey-red worm looking thing attached to his side. I put him in a hosp tank and picked 3 or four more of these out of my gravel....the ones on the bottom are half orangey, half white. They are definitely moving. I've looked around a little and think it is Camellanus (sp?) worms? I have 2 ADFs, 5 neon tetras, a female guppy, and 2 ghost shrimp in the tank....could it be something else maybe? (p.s. I have not fed live food to my fish..ever)
