Hello there,
I have a beautiful 4 inch Blonde Naso tang. 3 days ago it stopped eating but is still showing interest in a seaweed clip. I getting really scared as it is my one of my fav fish :sad2:. It is now gotten thin and if it eat some seaweed it would just spit it out :uhoh3:! Is there any way of getting is a fat tang like it used to be. I've tried soaking food in garlic.
What I feed is Green seaweed +garlic, Red seaweed, Purple seaweed, mysis shrimp (frozen), NLS, Live ghost shrimp (For my angler but my naso likes taste them).
Parameters
Nitrate 20 ( I need a water change!)
Nitrite 0
Ammonia 0
PH 7.8
 
I would do a water change like you mentioned. Nitrates and high phosphates will cause some tangs to go on hunger strikes. How long have you had the Naso? I have tried 2 in the last 3 yrs and wasn't able to get either to eat anything substantial and both died. I suspect your nitrates and phosphates are the cause of the problem
 
Do a water change and see if anything changes, if not I would suspect a disease of some sort or flukes possibly? Notice heavy breathing?
 
If over the two months your Naso has gone from being fat to thin, then either it has not been eating enough to keep on body weight or has internal worms. If you have the facility to do so, I'd remove it to a quarantine tank to see if you can get it eating in the absence of competitors. Generally when a fish gets thin and then stops eating, prognosis is not good though sorry to say. I find the Naso to be a very tricky fish.

I am sorry to say that I agree. A lot depends on how long the tang was in treatment at the lfs. Tangs don't do well in copper and develop liver disease.
Again I hope we are both wrong

The tang was only in the LFS for 3 hours. The tang has stopped giving "chase" to frozen food. It still would swim near the seaweed but when it was going to give a bite, it just swims off at the last second!
 
Is this a good thing? I threw in some goldfish for my angler and while one of them was swimming right nest to him he try to eat the goldfish? There is a little nip in it's tail (the goldfish!)

Not really mainly because you shouldn't feed your angler goldfish or rose reds... Ghost shrimp are preferred much more. Freshwater fish lack a ton of nutritional aspects that marine fish need. Try live brine shrimp for the naso and stop feeding your angler goldfish
 
I feel like many, if not most, blonde nasos must be caught using cyanide. I have had 3 in the recent past that ate a little but not enough, and after several weeks to a couple of months, passed away. no sign of any disease. I have 2 now that are very healthy, but I got them from a different vendor.

I have no physical proof of this, but I have kept fish for a very long time and I have never had trouble with Nasos until I tried blonde nasos.

Ken you make an excellent point especially if the fish come from Indonesia and I believe Naso tangs do.
In both cases we have stated, the posters naso is showing the customary signs of liver disease.

Interesting... And would make sense. I wonder if you can get a MAC certified blonde Naso?
 
It's an excellent point. Cyanide poisoning can take a while to kill, and losing weight would be a major symptom. I'd consider myself to be an expert fish keeper, with a number of difficult species sucessfully under my care, but I have been unable to keep a blonde Naso.
 
Still no luck! I got home and when i checked on him, his belly had gotten a bit bigger! The tang is still not wanting to eat! I wonder how it got a bit bigger...

Me too and I'm definetly no expert but I've kept 100s of tangs in the system I look after. They definetly don't last in restaurant tanks where kids are always banging on the glass

Could be internal problems still
Any chance you can pull him and put him in a quiet tank by itself. Feed it Vitachem and Selcon via the water.
Those two drugs have done well on blue tangs I have had in early stages of HHLE.
