Hi Everyone,

I need your expert advice. Recently, my whole goldfish tank was infected with Velvet disease (due to over crowding and lack of water change).  I was recommended Azoo Goldfish Magic Treatment. And within days, all were healthy again after 90% daily water change and lots of salts.

But my black Ranchu (attached photos) still have these whietish things forming around both of its eyes. It doesn't seems to be able to see (because I approach it, it doesn't response) and now it just hoover at the top of the tank. I am afraid I might loose it if I don't take any action.

Can anyone please help?

I still continue 90% daily water change, clean 2 of my 3 filters, and it seems to be eating well.
