It's really not that similar to the one I got last week. (That link is to a post I made for an ID request last week.) The tentacles on mine are much shorter and a little wider. Also, mine was probably dyed at some point; yours has a much more natural color. I agree with the others that yours seems to be a LTA, but I'm still not sure whether mine is really a LTA or if it might be a BTA. Either way, yours looks nice and healthy, and mine seems to be getting better too.
