You ask if they're loud do you. Well if one takes into account exactly
what
that "clicking" noise is, yes they're loud. That "clicking" sound you hear
is actually a sonic boom. Much as is the "crack" of a whip or airplane
breaking the sound barrier. Except the shrimp isn't moving that fast but
the
tiny bubbles that air created as it "snaps" shut it's claw are. Test have
been conducted by researchers at Hubbs/SeaWorld reseach Inst. that measure
the sound pressure these guys could create at being over 140 dB @ 2.5 cm.
dB wise that's loud enough to cause damage to tissue. Hence what they use
their talent for. To stun prey.

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.
