White Stringy Poop hanging from clownfish

[Bnortz]

Today i noticed that there is white stringy poop hanging from my male clownfish. I know this may mean parasites so should i transfer him to quarantine and treat him with para-guard or just treat him with para-guard in the tank. Does his diet have anything to do with it because I was on vacation for the past week and had the person wathing the tank feed my fish NLS pellets and flakes. I have seen poop hanging from him before, bit not as thin and white.

Thanks

Right after i post this thread i go check on him and the white stringy poop is gone. Also he ate fine today and is acting normal.

Just in case, should i soak some food in some of this para-guard?
