I had to reseal a leak in my tank so I had to drain and remove everything in it. I had 2 tangs, one died also lost 4 PJs all my snails. I had to redo all the live rock. Tang was put back in last night. He just swims back and forth, no sure if he can find any place to hide. The rocks are closer and not as many bigger holes spaces in the rock to hide. Just wondering if I should have made a place for him to hide and sleep in? Or is he looking for his buddy? So sad. I still have 3 clowns and 2 Splendid Dottybacks.
