That very well could be an anchor worm.

I have a sick fish in three different tanks all with different symptoms. My head has been going in circles trying to figure all this out

If he does have anchor worms, should I treat the tank that he came from that I just took them out of even if I don’t see signs of anchor worm on the other fish?

Honestly, that’s a big question that I have in general is if two different tanks were exposed to like I don’t know Cory Dora‘s from like the same breeder and one tank gets sick and the other doesn’t but they have the corridors in common. do you treat both tanks?
