Sometimes just like us, a fish has an itch that needs to be scratched. Or sometimes something non-disease related is irritating their skin. The problem is constant scratching can also be a symptom of a wide variety of diseases, with external parasites or Ich being the most likely. Did you QT the wrasses? If so, for how long and did you use any medications during the QT period? Have you ever looked closely at the wrasses to see if they have any tiny white dots on them that resemble sprinkled white sugar? Any head twitching or stringy white poo? Does the scratching seem to target a specific area of the body or head?[
Thank you for the reply. No, I did not QT the wrasses, nor have they been medicated. The scraping is very infrequent but it does appear to be directed to the gill area. I have not noticed any white dots, but will look much closer tomorrow. He has not shown any head twitching and the poo is brown as of tonight.
On another note, I had a pair of Rhombiods until yesterday. The female died after a couple days of not eating then a day of swimming erratically and finally what appeared to be complete loss of swimming ability. The appetite loss did not really cause me distriss but when she began to show inability to swim properly, I immedietly got her into a QT of Praztastic. Apparently it was not soon enough as she expired within a day.
I do not know how closely these are related but the chain of events has me concerned.
Thanks again for your help.
