Poor little mite.
I can't see the purple on the fish scales. Just keep an eye on the gills.
As if they turn purple you need to do an immediate water change. Also if they start to gasp, or signs of laboured breathing.
When do you finish medication treatment?
As I think I would maybe change to another brand of whitespot medication.
Interpet anti whitespot medication is good.
The medication nis finished and cannot redose till 7 days (Friday)
Interpet Anti white spot is what I used.
Will keep an eye on them and do another water change first thing in the morning.
