Flasher Wrasse - Cloudy White Spot on Tail

[DaveFe]

Hi all I currently have 3 flasher wrasses in QT, been in the tank for 5 days now. While observing I've noticed one of them has a cloudy white spot on his tail. It's small and can even be tough to see depending on the angle and background but wanted to get peoples opinion on if I should be worried. I've attached some pics below.

Some kind of bacterial growth? The only treatment my LFS is a brand called Prodibio, any feedback on that or should I buy something else online?

Thanks in advance, other than the spot he's the healthiest acting of the three spends more time swimming in the open than the other two and really goes after the pellets I've been feeding, you can see the smallest one hiding behind a rock in the background.

White-ish areas/spots on fish should always be viewed with suspicion. Bacterial infections seem to be running rampant in the industry lately - really bad. Here's @Humblefish treatment advisory for bacterial. I'd look over the list of antibiotics and make sure my fish med cabinet was ready in case of need.

Bacterial infections:

Symptoms - Sometimes it's self-describing: Popeye/cloudy eyes, fin & tail rot, dropsy (bloated fish), etc. But some other bacterial infections, such as furunculosis, hemorrhagic septicemia, etc., can have varying visible symptoms. Any redness or open sores/wounds on a fish should be viewed with suspicion. Also, a white film or fungus-looking growth may denote a bacterial infection. It’s important to note that in many cases a bacterial infection is usually secondary in nature to a parasitic infestation such as ich, meaning if a fish has been battling ich for a while then his immune system has been lowered. This makes infection more likely for many opportunistic, harmful bacteria.

Treatment options - Broad spectrum antibiotic medication i.e. one that treats both gram-positive and gram-negative bacterial diseases. Examples of this include Furan-2, Kanamycin aka Seachem Kanaplex, Nitrofuracin Green Powder, Triple Sulfa Powder, or a combination of using both Erythromycin & Minocycline. The latter can be accomplished (albeit expensively) by using freshwater Maracyn 1 & 2 and then doubling the dosage for saltwater use. When battling a particularly nasty bacterial infection, combining Furan-2, Kanaplex and metronidazole (ex. Seachem MetroPlex) can be very effective (and safe). Props to “hedgedrew” for enlightening me of this.

+1 on bacterial infections being rampant.

Absolutely brutal.

My flasher had the exact same spot on the same place. A week ago I noticed one little white spot on him. It fell off in 24 hours. I was on day 28 of successfully qt. This morning I woke up to a fish covered in spots very lethargic and not looking good at all. He's in ttm with nitro green powder now. Crossing my fingers but it doesn't look good. If I was you, I would start ttm today. And start an anti biotic during ttm. That will rule out ich and bacterial infections.
