My tank are filled with fishes and corals.
Recently, I found 2 of my fishes got some white spots.
Catching them are quite impossible with lots of corals and rocks for them to hide.
I did a full sump tank clean and WC yesterday.
Am thinking to do the same next weekend.
Is this possible to cure them?
I am trying not to stress the rest of my fishes and hope the spots will not spread.
What other ways can I do which dont need me to catch them up?
