Blotches on White Tail Tang

[CroMag676]

Can someone identify what is on the tail of this white tail tang? I got him 4 days ago. He is in QT with two wrasses. I am hoping to add another fish before starting a course of medication but the earliest the 4th fish could be added is Thursday. Other than the blotches, the fish looks happy and healthy. I have copper, Prazi, Metro, and GC at the ready. Thank you.

The other spots are on the glass.

Assure good water quality and diet
This often stems from bacterial issue. Many will feed nori and fish need’s meats also such as LRS herbivore frenzy, mysis, plankton and spirulina brine shrimp

Okay, I'll do a water change, thaw out some herbivore frenzy, and let him chill until I'm ready to medicate. Thank you!

If it continues, treat in separate tank with seachem kanaplex

Is Kanaplex not good for the wrasses or just unnecessary stress if you don't need it?

For wrasses, I prefer neoplex

Sorry, I wasn't clear. You said that if it continues, treat him in a separate tank with Seachem Kanaplex. Since he is already in the QT tank to be treated with the rest of the new arrivals, can I treat everyone with the Kanaplex or do I have to separate him? I planned to treat everyone together and add them to the display as a group to help with any possible territorial disputes.

I’d give him 1 sheet nori each and every day in addition to whatever else is fed.

I'm giving him about 2-3 square inches of nori daily. Should I offer more? He's still skittish, so I don't know if he's eating it but he is going HAM on the algae in the tank.

Start with fish only as this is rarely contagious unless you have a water quality issue

Nope that’s fine. Just wanted to make sure this food item is available, it’s an important contributor to health in this group.

I've been keeping him fed and doing water changes but things seem to be getting worse. The spots on the tail haven't gotten any smaller and there is a new spot on the left side of his dorsal. The spots on his forehead and near the pectoral fins could be from a disagreement with the PVC pipes but I can't be sure.

I started Kanaplex on Thursday and didn't notice any improvement, so I dosed again yesterday. According to the instructions, I can only provide one more dose. Today I made this video to show the fish's current state.



Sorry for the length but he didn't like the looks of my phone.

Great video clarity and LENGTH. The white tail appears to have injury from pvc or other object and has bacterial issue. The wrasses also appear thin and I will emphasize to focus on water quality and it appears you just began Kanaplex this past Thursday. It will take Kanaplex 2-3 days to BEGIN working on issue and often improvement day 5 or but not complete healing. Mori will not be the answer for these fish while in quarantine as for food source

They get .5 ml of Reef Frenzy, twice daily. Should I feed more?

Also, can I do anything about the PVC?

Feel the openings for any sharp edges and sand or file down to smooth

Update:
The infection wasn't improving, so I was advised to dose Kanaplex and Metro to the water column. After the first dose, the infection worsened. After the second dose, I checked the ammonia with an API test and found that my Seachem Ammonia Alert wasn't detecting anything and had allowed my ammonia to climb unnoticed. After a few large water changes, I got the ammonia down to zero, but I now have to change 25% of the water daily to keep up with the ammonia. This seems excessive for a 40-gallon system with a 4" tang and a fairy wrasse. I was unaware that Kanaplex and Metroplex would tank the nitrogen cycle. Some infected areas look better but the fish now has cloudy eyes with small growths in the center.

Under the advice of a LFS, I just gave the tang a 10-minute bath in HydroPlex. They say they use it for all their fish but, I'm concerned about its effectiveness against ongoing infections because the manufacturer states it is intended for newly acclimated fish. Has anyone had success with HydroPlex? I think I'm in fish-bath territory and would appreciate any recommendations.

Here's a video from this morning. What concerns me the most is the growths on the eyes. Edit: I have to do 2 x 25% water changes each day to keep up with ammonia. I'm feeding .5ml of herbivore frenzy twice daily.
