thats the video of what they are doing. They are digging in the sand the rubbing up against the snail shell that I have in there. Just started not even 5 minutes ago? They seem healthy have just eaten. I just added another cleaner shrimp and a mandarin goby into the tank today the shrimp took well and is already moving about the goby is hiding for now. My other shrimp molted last night. Outside of that the water is normal and they don't show any sign of disease.
Is this normal, ive had them over a month and they have never done this.

Thats exactly what it looks like now that you mention it. The bigger one does that in the Long Tentacle Anemone that I have. Weird thing is I have another anemone that they stay away from.
