the one's I have had in the past have all been quite loud IME I can hear
them at the other end of the house which is about 65' from the tanks.
its not a distractive sound thought and is not a "bang" sound but more like
a "click" sounds a lot like the glass of the tank cracking.

I am considering getting a Tiger Pistol Shrimp (Alpheus bellulus) and
pairing it with a Luther's Watchman Goby (Cryptocentrus lutheri) in my 7g
nano, but I am somewhat reluctant as I have heard that Pistol shrimps can
be
very loud and what amusing at first quickly becomes annoying. Is this true
or more myth than fact? Thanks.
