Heniochus diphreutes - Why deemed difficult?

[techreef]

When looking at Vivid Aquariums, they are one of the only vendors I could find that sell schooling bannerfish, or Heniochus diphreutes. But they deem them difficult fish to keep due to a high level of care required. Does anyone know why? Are they just poor shippers? Here's the website: http://www.vividaquariums.com/10Expand.asp?ProductCode=01-1813-S

I bought my five at a fish store. They looked very well and were eating readily and are still doing just fine in my brother's QT while I am in MI. I don't know how they do in transit but mine are all very well. Just feed them when they are hungry and they should do well.

Maybe they know something about how they are caught that we don't

So it's not anything like they are ich-prone or their long dorsal fin has weird health issues?

Maybe they just list all their butterflies as difficult? Heniochus are all pretty hardy though.

Maybe it was a mistake on the Web page.

I thought Heniochus fish were pretty well the easiest of the butterflies. I can't say for sure about H. diphreutes, but I had H. acuminatus with no problems at all, until I believe he was stung by my Volitan.
