Pearl Gourami Has White Sausage Like Poo

[lillykinloo]

Hi everyone! I was unsure of whether or not this would be an emergency, so I apologize for the post if this should actually be in the Beginner's Forum. I have a Pearl Gourami that has been doing well (swims around, eats, interacts nicely with the other fish). Today, I noticed a stringy white poo that was kind of shaped like mini sausage links. He/she doesn't seem to be acting sick, but I remember reading somewhere that white poo can be an indicator of an internal parasite. Is this true? If so, what should I do to treat it? Is this contagious for the Pearl Gourami's tankmates?

Ammonia: 0
Nitrite: 0
Nitrate: between 2.5-5
pH: about 7.2
gH: about 6
temp: 78 degrees
recent additions to tank: none
tank inhabitants: 3 Pearl Gourami, 5 Diamond Tetras, 3 Killifish Striatum
maintenance: twice weekly gravel vaccum with 10-20% water changes

Thank you in advance for your help!

White stringy poo can mean a number of things, constipation, bacterial infection, to internal parasites.
For now try some shelled peas to see if that clears it up first.
