Sick Percula?

[Absinthe]

Noticed a white stringy substance coming from the rectum of one of my percula yesterday. Only had the fish about 4 days, arrived in the mail on Saturday.

Any idea what this could be and how can I cure it?

Could be internal parasites...probably going to want to get him into QT.

That's not too unnatural in clowns, especially when changing diet, systems, etc. If it was wild caught, could be parasites.
