fish identification

[Michelin]

hi,

i have this fish since one month .....i know is a tang but i don't understandand what is.....

 

[Phildago]

Kole tang?

 

[Zionas]

White Tail Bristletooth?

 

[Michelin]

this now is darker....seems black but he is starting to change color specially on the top...seems brown but not 100 per cent sure....someone say nigracauda....but i dont think so....


could be Acanthurus leucocheilus ?

 

[Michelin]

White Tail Bristletooth?

but doesnt have dot in the face and he is not red....

 

[Zionas]

What color are it’s eyes?

 

[Michelin]

What color are it’s eyes?

there is an yellow ring externally...

Well, it has a white tail, at least it looks like it in your photo. Bristletooth for sure. So use those two tags and search away on your favorite search engine. I would second white tail tang.

I disagree, while this tang have a white tail, it is not a Ctenochaetus flavicauda due to wrong body shape, mouth shape and rounded dorsal and anal fins. It is not even a Ctenochaetus tang at all but one in the Acanthurus genus.
How big is he?

Y'all are barking up the wrong tree. It is one of the larger more unusual Acanthurus species.

 

[OrionN]

Consider A. bariene or A. thompsoni. I don't have experience with either but that they get BIG.

Maybe. Which is why I suggested searching . Below are tangs in the Acanthurus genus per your suggestion.

So now is not so big... Around 6cm but is growing faster than hepatus and also he eats continuously algae from Glass and rocks...

I already made a research but not so clear for me... Could be an hybrid? Now he is starting to change color to clrear brown...specially in the dorsal..

 

[OrionN]

Does it have a dark spot at the upper base of the tail which is a tail-tail sign of A. thompsoni. Some of the Thompson Tang have dark tail while other have white tail (regional variance or sub species). It is too small right now to reliably tell I think.

No any spot visible

 

[lebreef]

Looks like a juvenile Acanthurus nigricauda to me.

I don't know. you are likely to be right but I don't know much about these tangs

That’s Thompson’s surgeonfish, acanthurus Thomsoni.

i just saw this

What Tang is this?

Hey guys, I was wondering if any Surgeon fish expert out there who can ID this one It has blue edges above the dorsal fin and below the anal fin, yellow on the pectorals and also on the dorsal fins. My only guess is a Ring Tail Surgeonfish - Acanthurus Blochii Valenciennes But it has no yellow...

so i think he is the same fish....

Agree. Acanthurus Thompsoni.
