Clownfish Brooknella

[dado150]

Both of my naked clownfish have a fog look to them. They eat great, no scratching etc. No other fish have it. Is this Brooknella possibly?
Thanks

It looks like it. @Jay Hemdal ?

 

[Sharkbait19]

Anything added to the tank recently?
It does look like early brook.

They are nice looking fish.

How long have then been in the tank?
Any other fish sick?
Your parameters?
Any acclimation issues.
I'm assuming these are captive bred fish. SO the timeline of what happened/how they got there and what they were exposed to seems important. Sometimes clown get this type if 'picture' when first added to a tank with a parameter change.

Yes its brook.
At the onset, fish may scrape up against objects, rapid respiration develops, and fish often gasp for air at the surface as the gills become clogged with mucus. Very quickly the fish will become lethargic, refuse to eat, and its colors will fade. The most noticeable symptom of Brooklynella is the heavy amount of slime that is produced by a fish that has contracted this parasite. As the disease progresses, a thick whitish mucus covers the body. This will usually start at the head and spread outward across the entire body. Skin lesions appear and it is not uncommon for signs of secondary bacterial infections.
Typical treatment is a standard formalin solution is mixed with either fresh or saltwater in a separate treatment container. Initially, all fish are given a quick dip in the formalin at a higher concentration, followed by continued treatment in a prolonged bath of formalin at a lower concentration in a quarantine tank (QT). Of course, the longer the fish are exposed to the formalin treatment, the more effective it will be at eliminating this disease.
If a formalin solution is not available for immediate use, temporary relief may be provided by giving fish a FW bath or dip in water same temperature as display tank. Even though this treatment will not cure the disease, it can help to remove some of the parasites, as well as reduce the amount of mucus in the gills to assist with respiration problems.
Treatment is best done in a QT tank using either quick cure or Ruby Rally Pro. Ruby takes a little longer and initial treatment generally takes 2-3 days to really start going to work.

Thanks all. We've had them about 2 months. I'm guessing they are captive breed. Was just at lfs & didn't think to ask ‍. Added 2 pieces of coral, Coral Beauty & Yellow Tang that I had quarantined for 4 weeks from my other tank. Am I gonna have to pull all the fish for treatment? Don't think that's gonna happen with all the rock. There's 3 Anthias, 2 Mandrin, 3 Chromis, 2 jawfish, Coral Beauty, Yellow Tang, juvenile Blue Tang, 2 small hobbies & a Lawn Mower Blenny, Anemones, corals, CUC.

That should be 2 months.

Clowns like that don’t appear in the wild - they are 100% captive bred.
If it is brook, all fish would have to be treated to be safe.

I might be able to catch a few, but not all. Is it possible to treat with Rally in DT?

It is possible, but it is a poor second choice. The ingredients in Rally are effective against Brook, but the dose is too low. It has to be low in order to be “reef safe”. Logic also tells a it must be “parasite safe”.

I'm curious - his fish are showing none of the symptoms you mention - they aren't scratching, are eating, etc. Having heard that they were from an LFS (as compared to direct from the breeder - where there should not be brook) - does make it more likely - but - aren't there other things that can cause this appearance? Just trying to learn something - and help everyone else reading.

OP mentions fog look in addition to it being likely mucus

Yes - I know that. I'm asking in a tank bred fish - with no other symptoms - are there other things that can cause 'the fog look'?

 

[Spare time]

Seachem Paraguard seems to work very well for brook if you plan on treating them outside the tank (and of course if it is brook).

It was brook for me! OP, Same exact thing happened to me, it was brook. Please be careful

OP, when I was newer, my tank was doing great, I had an amazing captive bred hectors goby, really healthy, really active, ate everything. I got a clown, it was really fun and cool, I noticed the same things as you, but at the time I wasn't aware it could be brook. soon after, the clown died, the hectors died, somewhat fine one day dead the next morning. I don't want to scare you, but don't make the same mistake as me

I'm well familiar with that article. But, you're missing the point - I asked - Is there anything else besides Brook that can cause that appearance. I never said it wasn't brook, I never said it was anything else.

And the reason I asked @vetteguy53081 is because I think its educational for everyone to realize the reason for a diagnosis - and also a 'differential diagnosis'.

The article you presented is an excellent summary - and also educational - so thanks for doing it. That said - if all of this was as easy as reading an article - there would be no need for a disease forum, fish medics, etc, Right? (By the way that was a rhetorical question)
