Steve, thats normal behaviour for a BTA. The foot they will want to keep hidden under a ledge, in a cave, or in a crevasse, and they will only want to keep their tentacles and possibly oral disk into the light.
That's starting to be a well travelled BTA. Glad to hear he found a good home.
I think he has found a home finally ! ... just under a ledge where he can peek out ... Clowns are still with the hammer though
Cheers
