Congo Tetra Illness/Parasite?


I added some new fish and live plants to the aquarium with my congo tetras who have been living there for over two year. Last night, I noticed one of my female Congo tetras has a weird white thing on her eye, and the other eye has a smaller thing on it as well but it’s barely. I looked up all the common illnesses, and nothing looks like this.

I thought it might be a parasite brought in with new plant or tank mates because it looks somewhat wormlike to me, so I added a dose of API general cure this morning.

Otherwise she is acting completely normal and no other fish has this issue or any other noticeable problems. I have attached some pictures. Can you help diagnose?


Looks like dermosporidia, but don't know if that could be on African tetras.
