Watching my Knight Gobies and Archerfish is a hoot during feeding time. I put freeze dried krill on the bottom of my hood (just wet it and stick it on there) and then the Archerfish spit at it to knock it down. Thing is the Knight Gobies know its up there too...So the Archerfish swim around forever, faking like they might spit at it, trying to fake the Gobies out, because as soon as it falls into the water its a free for all as to who actually gets it. However does usually does a mad dash around the tank while trying to eat the krill. Looks hilarious, "It's MINE!!!". Sometimes the Archerfish just jump out of the water and grab it, heh just to make sure they get the first bite.
