Fully Grown Achilles only 6"?

My friend and I bought a long nose hawkish and hippo tang around the same time. His tank is twice the size of mine. His hippo has t really grown while mine is easily double the size of his. Yet his hawkish is called " A-Rod" because he is tremendous and must be in some drugs or something.
 
That's a pretty famously gigantic Acanthurus. Yellow fin tangs are huge. I think the biggest Acanthurus, if I'm not mistaken.

yep acanthurus xantherturpus are the biggest.. He is only 7 yrs old as well. and we have 3!!!! the newest one is the one i need to post pics of. Took him from somebody that had him in a 4 foot 150g!!! and still 19 inches after 5 yrs. trying to get him into west edmonton malls under sea caverns, ( 1400g Aquarium )
 
SDGuy/Peter,

On multiple occasions I have seen Achilles at the wholesalers at LAX over 9.5" and talking about the body size, not including the tails and the lyres. I would say Fishbase may be listing an avg size not a max size.

Even fishbase, which has some crazy max sizes listed, only lists the max recorded Achilles at about 9.5 inches. So I'm sorry, but you haven't seen foot long achilles tangs.



Hmm... Possible, but it's not like I have a ruler with me. It's an estimate, but the ones I've seen in Hawaii are pretty damn big. The "foot long" description was in general to the three as I've seen them in Hanauma Bay, on the same day.

I believe you. The Achilles I saw in Hawaii was awesome, definitely no where near 8-9".
 
ive seen them at 12+ inches (at least 4-5 of them on different occasions) here at a lfs...they get huge.
 
I've seen and owned a achilles that was roughly 12 inches in the past, I paid 200 for him about 5 years ago

I've seen those giant ones at the wholesalers before as well. The impressiveness of seeing them in person, and their overall round shape, IMO makes them seem larger. But I'll leave it at that... :) Regardless, it's a big fish when fully grown.

Last time I was there was in 1993, and I don't recall seeing any tangs. I wonder if they somehow "stocked" the reef... because it was just 1 species of green fish I couldn't identify at the time... they were all being hand fed all sorts of things, from pellets to peas.

Edit: looks like they must have made a lot of changes since I was there... just looked it up.. now you have to watch a film first? That's cool.

On the subject of not outgrowing a tank, I've seen a hippo tang outgrow a 125 gallon tank, it was well over 1' long. The LFS put it in a small tank that it could barely swim in circles, was there for over a week before someone with a 1000 gal system took it in.

Wow! Nice tangs. No aggression issues between all the acanthurids you have?
 
an occasional squabble but nothing serious.

I'm starting to think maybe certain regions in Hawaii have smaller "fully grown" Achilles. I mean c'mon 7 years and maybe .5"? :(

I would be happy with that! But I see you prefer larger tangs.
 
:lol:

My powder blue was bought in '06, and is still only a hair over 5 inches. I'm not going to sweat it. He looks just fine to me... albeit a bit on the chubby side :)

chubby? That does not look like baby fat to me. If he is a human, I would say he is morbidly obese.
 
Nice runt tfp. I have a hippo tang that was bought in 2010 the size of a nickel, and now Id say no bigger than 3 inches. Its in a 110g and there is not a lot of rock work. Fine by me as I really love the fish (second oldest) and would not enjoy giving him up.
It sleeps in coral branches since I got it, and if it grew to 8 inches, there is no way it could do that. Maybe natures way of keeping it safe.
 
I have a one spot foxface that was about 2 inches when I bought him 2-3 years ago. Now he is over 6 inches. He is in a 320 gal tank with lots of food to eat Their Max size is listed only at 7 inches. It is no brainer that fish with small mature size can easily reach their size potential in captivity.
