My betta has recently become ill with velvet, he still eats and stuff... But since he became sick i have noticed this... White fluffy/cottony wispy stuff coating my fake plant and ornament. And in some cases - the tank walls and corners.
Can someone please tell me if this is harmless at all to my fish?
I've done full water changes and scrubbed out the entire tank and ornaments but within a few days it just comes back! I have no idea what it is and I've found nothing on the Internet.
When I wipe some away, it breaks apart and floats around looking all wispy and fluffy, and makes my tank look dirty when it should be clean.
I also read that it may be over feeding, but this is definitely not the case with my fish. I feed him 1 pellet a day.
Help would be very much appreciated!
