Need opinions please

Hi

This male haves some white marks on him. I did treatment to the couple because of some parasites they had that killed all the frys when they turned 2 weeks. The guy looks healthy and dont have any other problems, i just dont remember him having all this before. He haves some alsonon his body
Is this normal on the guy or might be something? I just finished a treatment with parazin from waterlife and the guy is great except for this.

Thank you for your opinions
