Got this a few weeks ago and at first thorght it was a magnifica but now not so sure..Kind of looks like a BTA now..

This was when I first got it- looks like a magnifica

and now after it has placed its foot between the rocks with its mantle flat on the bottom of the tank... looks like a bubble tip?

Honestly, it looks like malu. Can you get a pic of the column?

I believe it is either a mag or bta. A closer look at the column would be helpful though like EC said.
