A while back while observing my tank happenings i noticed something dart across the bottom and go under some rocks. I tried to locate it so i could figure out what it was. Today while looking around i noticed a small head with antenna, all i could think was a cricket. A cricket?... Searching around the web i finally came across some images of creatures in a a reef tank. Low and behold, the cricket, an Amphipod and what  I've read there very good for tanks. Is this little guy like cockroaches where if you see one you've got more?

Most definately, check your tank out after the lights have been off for a while. Mine is swarming with pods, yours could be too.

yea i have a ton of tiny pods in my coral pico, along with some, not so tiny "crickets" lol, i have about 5 or so, and one even lives in his own tunnel, another has the heater claimed apperently... the one on the heater is red? any opinions on that lol

could be "scud " shrimp. good pods. i used to watch them dig dens by the front glass and raise their young.
