Grey patch on bicolor angel

Hi

Any idea what might be causing the grey patch which I discovered today?

Thanks, Paul

It looks like a bacterial infection. He will need to go to a QT more than likely.

Most fish can fight off bacterial infections if they are gram positive and the fish is healthy.

Do you have a QT set up? If you do I would treat with some bifuran and kanaplex.

Thanks for quick reply Justin, much appreciated. I don't have QT tank but will try to get something set up at the weekend

Cheers, Paul
