Do you mean Camallanus worm? If so. No. Seems however, given the length of the waste, it may have some internal parasite.

I'm not sure if it's columnaris specifically. Columnaris usually has a cotton like appearance. However, it does look like a bacterial infection of some sort.

That second fish definitely has it. Are these new to your tank? Quarantine them quickly if you haven't already, fish can bring in columnaris and wipe out ENTIRE TANKS in 48 hours.

treat them, but they are pretty bad, so i doubt they will survive
