I'm very happy to hear that! One of the two wennerae i received recently is still in a funk. In retrospect, i think if i had given him a longer and more gradual acclimation, he may not have behaved so unpromisingly. However, the other was acclimated the very same and is behaving much more comfortably, and i have even gotten to see him smack a hermit crab and a shore shrimp for getting too close to his burrow.
Thanks for the update.
