It is normal and adjusting, I got a 5" from LA same thing, and it closes up/no tentacles out, then they are out, they like moderate flow, Just remember, these things and I mean fish too are in an environment that is suitable for them, then thrown into a bag in the dark for a day, then a knew environment, I know you care, but I read so many Threads where the fish is in hiding, or like your leather, they just need quite time to adjust. Mine is in and out depending on the light cycle too.
