HI guys, I'm a new crayfish owner. My crayfish is fine until week ago I noticed she have white fuzzy stuff growing on her shell. Is this fungus? I tried changing water but the white stuff is still there.
Could you fill out the sick fish template to give us some more info?
This will be helpful to more accurately diagnose the issue.
By the way, WELCOME to Fishlore!
Definitely fill out the sick fish form.
Have you tried to rub them off with your thumb?
I usually do a salt dip or an alcohol wash if I see something funky on my crayfish.
