Brown stringy poo .... for the most part they're okay?

[SonRK]

I have a Tailspot Blenny and Firefish in QT about to end their QT period.


For the last 2 weeks I noticed that the Tailspot has brown stringy poo. Both fish are eating fine, and are hungry for the Rod's Food/PE Mysis in Selcon that I feed them. I already did a treatment of Prazipro, but the Tailspot still has stringy poo.

The Firefish seems to be fine, doesn't have any stringy poo, so either the parasites don't affect the firefish, or it's just an issue with the Tailspot with the food I feed it.

Brown stringy poo is likely not cause for concern. If it's white and stringy, it's a sign of possible internal parasites.
