ok this is the deal,friday night i here two click,saturday night i hear three clicks wich sounds as if the tank is breaking,wife hears clicking on a couple of occassions.i understand that it could be a couple of things.i have a few mud shrimp hitchhikers but never read about them clicking.maybe one or two hermits have turned dead but i still have a good number of them still alive.now the question is there is a piece of live rock alittle smaller than a football and i see what appears to be his tail could be redish but i think its more brownish.what would be the best way to rid him of my tank.the rock can be removed with out headache,so what the best to do before everything ends up dead.?
