Need Help - Christmas Wrasse Clamped Fin

Have a new Christmas Wrasse in QT for 3 days. Today he has a clamped fin and a white patch on side fin. See picture. Maybe has a white dot on tail fin. What can it be and what treats this? First time dealing with a clamped fin.

Did you give that fish a formalin bath?
Symptoms fit Brooklynella, Trichodina or similar protozoan ectoparasites.
I would give the fish a formalin bath ASAP and do a tank transfer.

Did a half dose of Paraguard. It is in the same tank as a flame angel and a fridmani psuedochromis. The wrasse is the only one exhibit any symptoms.
 
A full dose of Paraguard wouldn't be effective, a half dose for sure not.
Brooklynella is not an equal opportunity killer like velvet. Some fish are more sensitive to it than others. Also the primary way of infection is via direct contact, so the other fish may not have gotten it yet.
 
Does not make sense when seachem says Paraguard treats brooklynella. Starting with a half dose to start today. Full dose later tonight or in the morning.
 
I don't see anything out of the ordinary from the pictures. Is the fish eating and otherwise behaving normally?

You believe the claims of manufacturers, seriously?
They make outrageous claims all the time, but have no scientific studies to back up their claims.
Just have a look at all the claims those "reef safe" wonder cures claim...

The Wrasse is eating better than any fish I have had in QT. Ate the first day and hasn't stopped. Acting as normal as I can tell. The only thing I see is the side fin is clamped close to the body and he is not using it. The side fin also has white on the top third of it. I may see a white spot or two on the tail fin but that is a maybe. I don't know Wrasses well. Its mouth is open (not closed tightly), not sure how it is suppose to be. Respiration appears to be normal.

No, I don't believe everything I read or hear. BUT, you are asking someone who has owned several businesses, so I can answer your question from real world experience and not with flippant comments. Take a step back and tell me this. Do you think a company can go and put tons of money into marketing, labor, product manufacturing, machines, etc just to sell some stuff that doesn't work? How long do you think that business plan would work and at what cost? If you say it doesn't work, especially on a site like this, they wouldn't have a market for long to sell to. It is difficult enough to make money in this economy with a good product. Why would someone (or a group of people) try and make it with a product that doesn't work?

If you can post a video, that would be helpful with a potential diagnosis. Wrasses typically don't close their mouths all the way, so that's normal behavior. If the pectoral fin is not being used, it could be an indication of infection of some sort. I would lean toward bacterial, but without a clear picture (or video) of the fin, that is just speculation.

Why would someone (or a group of people) try and make it with a product that doesn't work?

That's a great question. Sadly, there are a number of companies that peddle their wares in this hobby that do just that. Seachem has a number of products that do work well, like Kanaplex and Metroplex. Both of those products are known antibiotics with scientific data to back up their effectiveness. Paraguard *may* treat some ailments, but the fact that they don't provide any studies to prove its effectiveness personally gives me pause. They don't even disclose what's in the bottle (glutaraldehyde + malachite green), which is a questionable practice in my view.

Yes, I do!
Many of these products can be manufactured in a kitchen or garage. There is not really high tech equipment required in many cases. I've seen it myself how a LFS produced his own iodine supplement by just diluting Lugol's solution and filling it into bottles and charging $20 for a 100 ml bottle that cost him maybe a dollar to make. Same was done with Strontium and other things. And these things actually worked.

Garlic has been debunked plenty of time here, yet products with it still sell like crazy.
Kick Ich and all the other none effective reef safe miracle cures have been debunked plenty of times here, yet they still sell quite well to uninformed aquarists or those who want to try despite the fact that they should know better...
Selling cheap bottles full of colored water for a premium is actually good business. Just because you and me are not shady enough to do it doesn't mean that there aren't enough others who do it.
 
I've experienced this with wrasses before; in fact, my C. rubrimarginatus had almost the exact same symptoms when he was in QT a couple months ago. I'd recommend a round of antibiotics - kanamycin or nitrofurazone. These meds are sold as Kanaplex and Furan-2 respectively.
 
You're welcome. It's good that he is still eating, but you definitely want to start treatment as soon as possible.
