I can safely say they weren't alive. Beyond that....I don't know how to tell the difference between poo and parasites? The only indicator would be that the Ringtail ALWAYS pooped, a lot. (he also ate the most, too) So when we moved him, I didn't realize he didn't poop in the bucket at all, until I saw the other two, who did. When removed from active flow, the stringy things collapsed into a blob in the bottom of the cup, but didn't disintegrate in any way, like I'd expect poop to.Just one observation: if you saw white stringy worms that were dead (and not poo) then they were likely expelled during the prazi treatment. If they were alive, they weren’t parasites, just normal critters that live in tanks. I’m still reading all the messages and trying to see what else I can find....
