Is this an internal parisite?

It's white/clear and they have not been eating. Just started showing any interest in food today.

How long has the tank been running?
did you cycle it?
if you can will you test the ammonia,nitrites, and nitrates of your tank,
how large is the tank?
what kind of filtration do you have?
what other fish are with them?
