achlies tang

Not sure where a fish's neck is, but this is what one would look like:

Keep in mind that Achilles are a difficult fish to keep, and very very prone to ich. Make sure to quarantine. Make sure it is eating before you buy. Also, a minimum tank size of 180gallons is recommended for these fish. They are extremely active swimmers - they live where the waves crash onto the reef.
 
Ok sorry maybe neck was the wrong term how about "throat"?

See in the pic how there is a lighter area below its gills?

But its alot lighter in color than the one in the pic alot younger too though
 
I agree, a purple would be a better choice.

Tangs can change their color somewhat, depending on mood, and also at night. A lighter colored chest can be a normal color for them to some extent. I have seen Achilles go very pale too with the orange staying bright.

But normally they should look like the picture.
 
I had always heard that too. I had a very large Purple and it was docile. Maybe swish a new fish with his tail a time or two, then go back to normal. Guess it depends on the individual fish.
 
Tangs are normally aggressive to newcomers, then they will usually settle down and get along. There is always the rogue that won't get along. I had a Sohal that was pure evil. So again, other than the initial aggression that always happens when a new fish is added, generally tangs will get along. This goes for tangs as well as other fish.

Many people will say not to mix tangs of the same body type, like a yellow and a purple. I have not found that to be the case, it seems that tangs will generally get along if they have enough space.
 
My purple will fend itself when terrorize by others but he is not a bully by any means. Both my yellows are worst. My archillis is a bully and will chase both my kole around and fend his terriority w/ my blochii who is twice his size. Purples are much hardier then Archillis. And yes...it is normal for Archillis to have that white pale underneath its throat area. At the end of the day...I think that aggressions is hit and miss w/ these fishes. Just like human races...these fishes are also sterortype and classified in their own ways... However, both are good choices of tangs...good luck!
 
It is quite normal for AT to change color at different condition. My AT will get this pale white color when it is upset or showing aggression. Sometime the AT whole body will turn to pale white when the cleaner wrasse is doing the cleaning.
