Do my fish have a parasite?

I have a 40 gallon breeder heavily planted with pressurized co2.

Levels
Ammonia 0
Nitrite 0
Nitrate <5
Ph 7.0

Water steady at 79-80F

Eheim 2215 canister filter

I currently have
10 neon tetras
1 small angelfish
2 dwarf gourami
5 Dalmatian mollies.


Over the past couple of weeks I have noticed an occasional white stringy poop from my angel and dwarf gourami. They usually have normal looking feces with the white stringy attached. However they all have full color, eat regularly (and ferociously I might add) and are all very active. However the white stringy feces have me worried about internal parasites. I just wanted a 2nd(3rd,4th, etc.) opinion

 

Anybody got any clues?

 

You could try to worm them first. To my knowledge worm-meds don't mess up bacteria aso. What are you feeding?

 

Flakes and 2 times a week I alternate between freeze dried bloodworms, fd tubifex, and fd brine shrimp

I've ordered some medicated food as a precaution

 

What does it contain?
You need food with metronidazole.
Putting it in the water will do no good either, so if you buy the antibiotic in powder form, mix it with their food and let sit for 30 minutes to absorb.
More often than not stringy poo is just a sign of bad batch of food or some internal bacteria going on. Internal parasites are more rare than people seem to believe.

That's what I thought too. I had read where they also can get white stringy poop from eating vegetation and they all do that quite a lot in my planted tank. And they show no other symptoms of disease. As a precautionary measure though they did eat that medicinal food for the recommended time. So they should definitely be good now.
