    GPG Spot-lighting at Night (Part 1) Went for a wander with the torch last night, and see who I found floating next to a filter outlet - Yes! "G for George" in all his his grey glory ! He seems happy enough, but is extremely shy during the day. Grover (fish hunting by torch-light again later in the week)

    Robo-Gourami Wanted... Saw this today - Robotic Fish and thought the GPGs could give robo-fish "What For" in the Billabong. Grover (on the hunt for fishie technological advances) Another article in "WIRED" has this quote (ha ha) - "Thus the fluid energizes the fish. But it also acts as a traditional hydraulic fluid, in that it transmits force in the tail and pectoral fins. When the pumps push the fluid to the fins, they bend back and forth to propel the robot. The pectoral fins work in the same way to steer the fish left and right.This doesn’t move the robot particularly quickly, mind you: The fish can cover about one and a half body lengths per minute. “It would definitely get eaten if it were in the ocean,” says Shepherd."
