I have a yellow banded opossum wrasse in my reef. I QT'd it with Cooper power at 1.75ppm and at a lower salinity for a month when he first arrived from live aquaria. I did not use prazipro on him because I:
A) didn't know what I was doing
B) didn't see any symptoms of parasites.
Now the wrasse has been in the reef for ~6 months and today I saw him scratch against a rock twice in quick succession. It's possible that he scratches occasionally but I've never witnessed it until today. Do fish sometimes scratch without parasites or disease to blame? I read posts about itchy fish, but all the cases I've seen seem to be much more severe than what I witnessed.
The only other health thing I've noticed with this fish is that one time he passed a transparent mass in his stool. I was initially concerned but it really just looked like partially digested mysis bits. Now I'm worried it's connected to the itching.
Any one have insight into this kind of thing?
