Is stringy white poop alone enough to diagnose parasites?

I highly doubt that she has parasites, the tank has had the same inhabitants for months. It makes more sense to me that she ate a shrimp or snail instead of the pelleted Betta kibbles and that's why she alone had this pale thin string of poop. But is it possible for fish to carry parasites yet be completely asymptomatic for so long? Should I treat anyway?

 

No, but it is a good symptom of internal parasites. However, if the fish in question still eats and doesn't look skinny, I would say do nothing at first and just keep a careful eye on her

 

Do you feed tubifex worms?
How many months? I have seen camallanus and or callapria last 2-3 months before it took over and was visable.

 

No tubifex. Occasionally frozen bloodworms and brine shrimp and lately, live mosquito larvae.

 

Maybe the live mosquito larve is the culprit? Or they could have just came in on a plant or bottom feeder or shirmp?

 

No bottom feeders. Shrimp have been in there since the beginning. Plants...it's possible I suppose. With the mosquito larvae it was my understanding that any parasites attributed to mosquitoes are carried by the adult females and transmitted through the bite. The eggs and larvae should be clean as long as the environment is clean.

 

Also you might want to mention that you are raising your own in a bucket and not netting them out of a swamp. Alison

 

True! I even do water changes on the buckets so they're not breeding in the same water for months on end

 

Aquaphobia how is she doing? Is the poop better, worse?

 

Everything's back to normal! Which means I guess that she probably did eat one of my RCS:-\
