Physical or bacterial damage?

[Ali-F]

Hi All,

May I ask your opinion on this picture?

The chocolate tang deleivered to me like this. After communicating with the supplier to know why would he send damage/ sick fish like this. He said that this is a bag damage happened in transportaion.

I am not sure if this is true or this is an erosion because of some bacteria.

What could be the issue? So I can treat it accordingly.

Thanks in advance

Mechanical injures will often be followed by bacteria issues. Many times the fish will manage this by them self. Clean water and a stess free environment.

Sincerely Lasse

Looks bacterial i would treat with kanaplex, Sulfaplex and Furan-2. Sulfaplex is very good for mouth infections.

Edit: - keep the water quality clean.

It does look like it could be shipping damage, but I would still treat with a broad-spectrum antibiotic to prevent infection since it is pretty severe.

Edit to add:
NFG powder, or the “trifecta” of kanaplex, metroplex, and furan-2 are both good options. Sulphaplex is another good antibiotic, but it’s a bit more harsh on the fish so not sure I would mix with the others... but that's my personal opinion.

Then I am on the right track. I added 5ml of paraguard upon arrival and also treated him with API TRIPLE SULFA.

Thanks @Lasse @Bmwm235i @ngoodermuth for the quick reply and the advice.

I keep NFG powder on hand for this exact condition. It works great on fish with damage from shipping. Very popular with many LFS and wholesalers for this same use.
Best of luck with your fish. Triplesulfa is very good as well.

How long before I see a noticeable improvement? @Big G

Most saltwater fish are slow to respond to antibiotics. Give the fish 10 days of treatment to allow time for the fish's immune system to start working on repairs. Remember, antibiotics don't cure anything, they just give the fish's immune system time to do its work. In the meanwhile, feeding the fish excellent quality foods (frozen and/or live) and some vitamins like Selcon/Zoecon, and pristine water conditions will go a long way to bringing your tang back to top condition.

@Big G Treatment duration is about 6 days long. But still, I will keep the fish under observation for another week to ensure full recovery before I start treating the white spot.
