Emperor Angel (Parasite, Worm, Other?)

[mwrobers]

Emperor @ 2 weeks in DT eating well (frozen Hikari algae and krill, NLS pellets, seaweed sheets, and live rock algae). I soak food in selcom twice a day. White string was a loop, but sailfin nipped it in half. As I type, the emperor pooped the white stringy thing out and pooped regular. Should I be concerned?

Sign of internal parasite. I can't think of the med right now. Also heard Prazi-Pro may do the job also. Maybe post this thread in the Fish Disease Forum.
