Looks like they're sharing bits and pieces of wrong information, most of it from the same original source.
My biggest issue has to do with the photos -- the red anemone is clearly a haddoni (though it's in the rockwork which is a bit odd). The blue nem also looks like a haddoni. One of the most common questions I see on this forum when it comes to carpet anemones is how to ID a haddoni versus a gigantea. These photos will only confuse people.
Other issues:
"Newly arrived anemones are not a good idea to purchase... Put a deposit down and leave prospective buys at your dealers for a good week."
This is not true. A week in a dealer's tank could kill it, while a week at my house in QT with Cipro could save it.
"Stichodactyla haddoni in a tank in Germany... artificially dyed... and likely to die... avoid such artificially colored specimens." [describing a neon green haddoni]
I've never seen a dyed haddoni. Furthermore, neon green haddoni are seen fairly often.
"How much circulation is advised? Something short of ripping the animals off the rock, but complete and vigorous, non-linear... "
No, it's even questionable if gigantea like a lot of flow. Haddoni definitely do not.
"Carpet Anemones, by virtue of their large size, sometimes "sticky" nature and general lack of hardiness in captivity are not good candidates for asexual propagation (fragmentation, cutting...). But sometimes they do this themselves..."
I don't think we need to re-visit the issue of propagation, but those who read looking for a reason to try something, may read the above statement as a reason to cut it since "sometimes they do this themselves" when the reality is that there isn't a SINGLE case of this happening in captivity that resulted in two healthy carpet anemones.

Here's a few more I pulled from the other articles... (and keep in mind that the second article references the first one)
"Like Stichodactyla haddoni, the gigantic carpet anemone will need a deep sand bed in the home aquarium"
"The gigantic carpet anemone occurs in blue, red, green, purple, and pink color morphs." Red and pink?
"Carpet anemones are voracious eaters, and all species should be fed weekly to bi-weekly, depending upon the health and size of the animal and the lighting conditions in the aquarium."
"If you are buying a carpet anemone from a local fish store, have the dealer hold the animal for an entire week at least."
"This anemone can easily cost between $30 for a tan one up to $400 for a red one" A red gigantea, really? I know of only one possible candidate.
"The S. gigantea have not been bred in captivity and rarely do they split on their own. Propagating is not recommended. Anemones in general can multiply by sexual and asexual means. One way is using fission, which is when they actually split in half from the foot or mouth to form a clone, although the clone is its own animal, similar to twins."
I do agree that the articles are good for general consumption, but the reality is that portions of the articles, when taken out of context, can lead (on the extreme end) to the death of the anemone. Rather than point people to these articles, I'd rather that they read the sticky above or ask people in the forum (actual owners, not from authors who may not even have carpet anemones) -- or better yet, do a search on RC first!
