My tank clicks at night

"baitshopboy" --- to answer your question, a goby & pistol shrimp pair up because they benefit eachother mutually. In biology, they call this a symbiotic relationship. So, in the case of the Goby & the Pistol Shrimp, the Goby has better eyesight so can keep watch for predators. Hense the name Watchman Goby. The shrimp in return is better at burrowing the cave that they both use for protection. They rely on eachother's strength, so to speak, to increase their protection ultimately from nature's predators they face in the ocean. Facinating to watch in tank.
Since they Pistol Shrimp is close to blind, the Goby communicates with shrimp to retreat to cave by swishing its tail against the shrimp's antennae. All the while, the shrimp is constantly keeping their burrow cleaned and accessible.

U might want to get that out real quick... the noise is them pecking at the bottom glass of ur tank... If they keep doing it... It will crack the bottom.... and then u know what happens.... Ive seen it happen.....

how often have you seen it happen?
Dr Roy, a big name in stomatopods (mantis shrimp) and the one that answers questions on here, said he has rarely seen it happen - and only with a large - 5''+ peacock mantis - this is a myth that keeps getting spread and gives mantis a bad name...
be informed before you make a knee jerk statement regarding hitchhikers
and YES - there are some of us that love mantis - i actually have one that lives in my DT quite nicely and gets along with everyone!
(sorry bout the rant - i just get tired of ppl blaming so much bad on a creature that really doesnt deserve it)

PS - here is a thread with a link for ID

Does the red light really work? I have heard it is complete shenanananagians?

so not believe emeralds click, at least at some sort of consistent level.

Yes, red lights work. If you sit for 50 minutes or more in the dark a chemical builds up in your eyes that enhances your night vision, increases light sensitivity. The red light will not cause this chemical to go away. Any other light will cause it to instantly vanish. My theory for nocturnal creatures is that since it does not destroy night vision they don't feel an increase in danger by being out in it.

You ever notice in the movies that war ships always have the bridge lit with only red at night.

That's a pretty good site on mantis shrimp. It has a review of a 2001 British movie called Crust. The film is about a 7 foot long mantis shrimp (of the "smasher" variety rather than the "spearer" type) that is trained to box with humans. Now that I've heard of this movie, I'll have to try to find a copy.
