Help! Does anyone know what is going on with this fish??? I've never seen anything like it. Fish is eating and behaving normally but these things have grown and keep growing

Looks like an infection of some sort; I would definitely put that fish in quarantine. I would also be very careful catching it; if one of those pustules were to burst it could infect the entire tank. Really don't know how to treat that; I have never seen anything like that. Antibiotics maybe?
