Annularis Angelfish Has A Worm

[dustinwerk19]

alrighty so I purchased this Annularis Angelfish from my LFS a few days ago, he has been eating fine until today, he’s still acting normal, i’ve never dealt with worms before so should i just run some copper through the tank? help me out here guys, thank you

Do you see a worm in his excrement? Do you have a quarantine set up? Is your tank a fish only or a reef tank?
