tang problem

[Docsb79]

My yellow tang has shown the brown discoloration for a few weeks now but was eating nori, flake, and frozen food fine. As of yesterday he is only eating the frozen. Is this HLLE or some sort of fungus. None of the other fish are showing any problems.
Thanks for any help

definatly not an expert but did some searchign for you and appears to be bacterial infection

If you haven't already, I would get that guy into a QT with nice clean fresh saltwater. It's nice and fat so it will have a fighting chance. From there, determine the treatment, I'm leaning towards a bacterial infection, but it's hard to say without actually seeing the fish.

how big is your tank? what other type of fish do you have? how long had you had the tang? what do you feed him? do you have a full pic of your tank?

He's in a 75g with a 6 line, 2 bluegreen chromies, and a false perc. Will try and get a full tank shot later tonight when i have time. I feed frozen krill, some flake food for omnivores and green nori from grocery store. I had him in QT and treated with copper because I had thought it might have been black ick but had no effect so put him back in DT thinking it might be HLLE and he would be better off in there and just feed good but now he isn't eating the nori at all just the krill.

septicema? oodinium has even caused a couple fish I had to look like they had "rust" on them..

 

[Docsb79]

Talked to LFS today and he wasn't sure but recommended trying a antibiotic. Will give this a try and see if it makes a difference.

yap go with anti biotics on its food and try to feed it as much as possible, go with garlic to make him eat.

 

[Pallan]

the antibiotic to use ive heard is marcryn 2 (not sure of spelling there) and dose in a QT tank otherwise you'll hurt the rest of your good bacteria in the tank
again no expert here just looks like something ive seen on another site

 

[OasisTF]

My educated guess would be Bacterial hemmorrhagic septicemia and can be treated with Oxytetracycline.....mix it with the food and seachem focus

Hope this helps and good luck

Definitely mix the antibiotics with the food, they are far more effective that way. Dosing the tank leads to wasted medicine and the fish not getting enough to fight off the infection.
