No need to apologize Neal!! I was just being my anal retentive self. Sorry. I was pretty sure they just showed up on your list as "carpet". I guess to be fair, wholesalers probably deal with who-knows-how-many in a year, and they don't have time to analyze every single creature that comes in. (Well, that, and maybe most customers aren't as picky about ID's as others.
)
FWIW, here's why I think they're gigantea.
1) The tentacles look too large to be haddoni. Most of the time, the tentacles are way longer on gigantea. (Think "shag carpet".) However when new to a tank they can "pull in" and look very much like a haddoni. But even then the overall scale is just larger.
2) Gigantea's like to bunch up or fold up like shown in the picture. A haddoni is more likely to lay flat. (Exceptions apply of course).
Generally speaking, the best way to cinch an ID is look at the verrucae (the little dots on the sides of the anemone). Anemones use verrucae to attach temporarily to substrate. Gigantea's will have prominent verrucae in a constrasting colour (usually purple). Haddoni's will have smaller verrucae and usually the same colour as the rest of the pedal disk.
Here's an example of verrucae on a gigantea:
Usually if you can see the verrucae, ID'ing the carpet is a snap.
Incidentally, mertensii will have usually orange verrucae, in little dots or circles in shape, and will extend the entire pedal disk top to bottom (whereas gigantea will have them concentrated near the top). I have yet to see a merten's carpet in person. Seen a couple pictures mostly on RC, they seem to be fairly rarely imported.
Also -- apparenly only haddoni's can show variegation colouration -- so if you can see two colours in the oral disk, it's likely haddoni. (Or so I've read.)
