Question about redness in Chaetodon auriga Butterfly
Mr. Fenner,
<Hello>
Thanks again for the great advise on purchasing the Iwaki circulation pumps and oscillator/wavemaker for great water circulation! 
<Glad the folks here could be of assistance>
All of my fish are very healthy since I bumped up the circulation in my tank. I have a 5 month matured 180 FOWLR system, current inhabitants, 1 bi-color angel, 1 tomato clown, 1 velvet damsel, 2 Chromis, 1 Xmas wrasse and I just purchased today a large Chaetodon auriga Butterfly. I have a question... the Auriga is about 7 inches large in size and before I left the store he was perfect in color, fins exceptional condition... 
<Seven inches? Shame on the collector... such large specimens should be left in the sea... they don't adapt well to captive conditions or ship well generally>
no external problems whatsoever. I arrive at home 10 minutes later , proceed to drip him for about 45 minutes with a .019 salinity, same as what 's in my hospital tank, then placed him in. 
<Mmm, then why the dip?>
I now see what appears to be a subtle redness, not too much, around the mouth and fin bases. Can this be some internal damage due to the trauma inflicted during the bagging and trip?
<Yes, or residual, partially healed damage from previous holding and shipping>
When the store salesperson scooped him in the plastic container I noticed the fish flapped around quite hard against the glass and he may have injured himself. I am very concerned about the redness ... is it internal bleeding?
<Possibly>
Will he recover from this with good treatment , good water quality and vitamins?
<Again...>
I don't want to lose him. Should I place him in my main tank since the environment there is much better... no nitrates, temperature perfect? Please help!
<I might do so>
This is a section that I read from Wet Web Media on Auriga's Appearance....
Appearance:
Reddening of the mouth or fin bases disqualifies a prospective purchase. Due to their sharp pointed snouts, threadfins, indeed all B/Fs need to be packed in large bags and laid on their sides in transit. This provision reduces the chance of damage from slamming during handling and shipping.
<Not surprisingly, I totally agree... with myself. Bob Fenner>

Robert,
Will this fish recover from this with good treatment, good water quality and vitamins? I can return him today if there's little hope.
<For such a large specimen, being caught at this size (seven inches if memory serves), there is "little hope". Moving it will not likely serve to save it... unless perhaps we were in Hawai'i. Then, there I would replace it to the sea (which wholesale collectors due sometimes when a number of organisms "breaks down" in an attempt to return them to health, redeem themselves. Bob Fenner>

New Tinker BF processing
Hi Guys or Gals,
<Matt>
    I have a quick FOWLR questions.  I am purchasing a Tinker's Butterfly for my 250 FOWLR and Mr. Fenner once recommended to me NOT to Quarantine my Pakistani B'flys.  Should I take the same steps with the Tinker's or should I quarantine?
I always quarantine my fish for a period of two months.  But my Q tank has no live rock which seems to be essential to the Tinker.  What should I do?  
<I would NOT quarantine a Tinker's... WOULD treat as stated for the Pakistan>
By the way,  What do you folks think of the hardiness of the Tinker?
<It is about as solid a species of Chaetodont (as are all subgenus Roa) as there exists>
Thanks a ton and Happy Holidays,
Matt
<Bob Fenner, out in HI, saw two Tinkers in pretty shallow... about 120 feet, yesterday>
