help what is this on my fish

idk what this is

 

fungus, perhaps marine velvet.

 

how do i treat it

 

I think its brookynella

 

it almmost looks like corrosion it looks also like his skin is peeling

 

pimafix, if you don't feel like catching him and putting him in a hos tank and treating with a non-reef safe medicine

 

It looks like your tank is quite new how old is it ?

 

This parasite infection is commonly known as "Clownfish Disease", because it is so frequently a problem with clownfish, especially wild-caught. Although it is seen most often in clownfish, other species can suffer from infection. Symptoms are usually noticed on only one or two fish to begin with, but it can spread rapidly. Brooklynella hostilis is fast acting and can kill in just a couple of days if left unchecked.
Some possible visible symptoms are the following:
• Increased mucus production
• Loss of appetite
• Turbidity of the skin
• String-like material hanging from the fish
• Increased respiration, or even open-mouth gasping
• Hyperactivity in early stages
• Hiding or reclusiveness
• Cloudy eyes associated with secondary bacterial infections
• Faded colors or discolored areas
• Lethargic in late stages
• Hanging at the surface or laying on the bottom in late stages of infection
• Rapid weight loss associated with dehydration, as fish lose their ability
to osmoregulate.
• Loose scales
• Secondary bacterial infections

if it is brookneylla you have to do a formalin dip any other treatments won't work.
i don't thank it is that though unless all your fish have it, it is very contagious and very deadly and very fast

 

is a year old that just happens to be a new addition...shelf rock i found it on a beach when i went to fiji

 

oh i dont know if it is brookynella, but it def looks like a parasite, but not of the white spot kind i.e. - crypto. Could be amyloodinium but you dont normally see it so .......... well like in that picture until its in its late stages.
I lost a whole tank to it as i couldnt identify the parasite until it was too late.

But if Kfamous, your fish has suddenly developed this quickly, then im willing to bet its not velvet, but brookynella.
