Saprolegnia is literally everywhere. Not technically a fungus anymore, by the way. Itīs now in the class Oomycota.
I wouldnīt be concerned about the pressence of Saprolegnia (because as i say itīs everywhere anyway and should not be a concern for a healthy animal), but rather about the possibility of having introduced other patogens/parasites with the goldfish. They have been known to carry deseases to which axolotls are susceptible.
