Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
Here's a thought. I'm seeing a pretty open tank. Do you have places for the tang to hide during the day and wedge itself into a tight spot to sleep at night. My tangs like to hide and swim through caves, and at night they wedge themselves into spots I can't believe.
