Help! Naso Tang!

[MSB123]

My Naso tang ( I got it on Wednesday of this week) is laying on the bottom of the tank. This has been like this for over an hour. He hasn't been eating and last night he was breathing a bit heavily. I gently picked him up, and he has no buoyancy- he just fell back to the bottom of the tank. What should I do? I have kept many tangs, but never a Naso tang?!

When was the last time he ate? What did you feed. Tankmates bullying him? What size Tank?

So he is in quarantine? Can we see some pictures of him. Notice and white spots on him? are you treating him with any medication like copper?

 

[MSB123]

Yes, he is in QT- Ill post some pics- no white spots- dosing prazipro and cupermarine like what I always do

 

[MSB123]

He has no signs of anything on the outside

 

[Dilan Patel]

Have you tried feeding nori? how thin is he?

 

[Dilan Patel]

Sorry just saw you have tried that

 

[MSB123]

He is fat, I have tried nori, he wont eat it

 

[MSB123]

He only has eaten nori once, the day after I got him

 

[Dilan Patel]

Frozen food? I know these are some basic question and I am sure you know this but just making sure we covered all the general options available.

 

[MSB123]

Yeah- tried frozen ( all kinds) nori, pellets, flakes, everything

What's copper level at?
How quick did you get there?

When was prazi last dosed?

 

[Dilan Patel]

At least he is fat which gives you some time to hopefully get him to eat.

Copper is o.4 mg/l, prazi was dosed on thursday evening

 

[cmcoker]

So did he quit eating before or after the prazi dose?

Over what length of time did you raise the copper to 0.4? And just checking, but you are not using the API copper test, correct?

Im using the seachem copper kit- the one meant for cupermarine- i raised it over 48 hrs, I dosed prazi and he ate after the dose, only once though
