My Yasha goby has swam head first into a pore size hole in the rocks. Just his tail and end of the banner is sticking out. He's been this way all day. Every once in a while I see his tail thrash. It's not a hole that goes through the rock. Should I leave him or try to gently pull him out? I normally would just let nature run it's course and wait it out BUT I bought this fish locally and overpaid ($50)for it only because I have wanted one for so long and couldn't believe my eyes when my LFS had two last night.
