Is this a Mertensi anenome?

[Jetbkk]

I just bought this anemone here in Bangkok. Like usual, their English was limited and they could just say it was an anemone. I believe it is a carpet anemone and it looks like it could be an mertensi anemone from looking online.

Do any of you know? BTW, this photo was taken within the first 30 minutes in the tank so it is probably a bit pissed off and not settled in yet.

It is pretty small (maybe 4.5- 5 inches) but I read that Mertensi is the largest species?

Thanks for any help id'ing this one.

looks like a bleached gig. Try to stay away from the anemones that their color resembles White or yellow, its due to a loss of zoa.(the symbiotic photosynthetic algae that lives inside it and provides it with nourishment)
