sebae ID please

[taylor t]

I think it's a sebae, I'm just not sure which flavor it is. I think it's a crispa. When I got it a couple months ago, it was 1/2 the size and the tentacles were little nubs. They've gotten longer, and the nem's doubled in size. I'd just like to know which one it is for sure. Anyone know for sure? Thanks.

The foot goes through the sand and attached to the bottom of the tank.

After looking again, looks like malu to me now.

I'd have to say malu for now. Any pics of the underside?
