I LOVE my pair also. I have the same pair as NM Reef. I originally bought a pistol shrimp and spotted goby already paired from LFS, but the poor Goby was beaten up by another fish so badly it died.
Then I had Big Dig (shrimp) all by himself for months until yesterday, he now has new buddy. The Goby found him and went into his den the first day in the tank. :jumping:
Mimzy- they would be great to watch in a 12 gallon, less obstruction from live rock. I love mine in my 29 so much I am considering getting another pair to put in my 16.
Great pics everybody, keep em coming!
