I originally posted the photos above, and I can tell you that in person, both anemones were stunners. But they were both very different as shown in the photos. In the top photo, you can clearly see the pointed tentacles (see the nem on the very far right). The nem in the bottom photo had tentacles that were not tightly clustered together.
I'm glad that these threads keeps popping up, since I feel that it is very important to spread the knowledge that we've acquired. I don't think dealers are misleading buyers on purpose, but it's important to clarify that the red nems with the green mouths ARE NOT haddoni, and should not be sold as such (and should not command the price tag of a red haddoni). I think mini-carpet is an appropriate term since there isn't confirmation that it is a mini-maxi, though the pointed outer tentacles cause me to think that these are S. tapetum or a close relative. I can also tell you that the selling price here in CA is about $50-$75.
Regardless, I'm glad that these are available, since I think they are a great addition to our reef tanks. From what I hear, they split regularly and are easy to care for.
