Resolved New pink square Anthia is Sick (ID This?)

He has 1 of these on both sides of his body. This picture is of the worst side. I noticed it yesterday and now its worse. What is it?

 

No idea actually. Doesn't look like ich. Maybe some other type of parasite.

Do you have a cleaner fish or shrimp?

 

He is in my QT tank so no I have no shrimp there.
I just bought him Thursday along with 2 females.
I QT all new inhabitants. The females look good, no
injuries. They are all eating fine although the male is
more shy and hides alot. But from what I understand
this is very common for the pink square anthia. I just
need to figure out what to do and try to heal him.

 

This guy is going to go down pretty quick! There is another spot forming on him. I hope this dont spread to the other 2 in the QT tank

 

A fish medicine containing praziquantel will kill flukes

i.e. Prazipro, API General Cure, Clout, etc.

 

Thanks i will get some
