How does this get in my tank in the first place? This tank has been up for almost 3 years, and the clownfish were the first fish I added!Brook or late stage ich. White light pics will help.
Ich, brook, or velvet all cannot be treated in the display tank, but need a separate qt for treatment and for the tank to remain fishless for a set amount of time.
Brook requires formalin for treatment.
This is Brook and what looks like secondary bacteria. The most significant sign is the amount of slime on its body. The thick mucus on its body is a second sign which is noticeable on the fish. This mucus generally starts at the facial area as well as gills and spreads across the body producing lesions as it progresses often confused with ich and can turn into secondary bacteria. Other symptoms will be lethargic behavior, refusing to eat and heavy breathing from the mucus.Hi! I just noticed this today when watching in my tank. It looks like dry skin almost. I haven’t noticed anything on my other fish, so I‘m hesitant to say its velvet. I also don’t have any kind of QT tank; even if it WAS velvet, is it even possible to treat it without a QT set up?
I believe fish can have dormant disease in their systems that their immune system keeps in check however under stress their immune systems weaken and the disease goes from dormant to active.
