What else? You need an Asian fisherman fishing in the tank.There is a place in the world for clown puke gravel. I don't have it in my tanks, but still like it. I see a tank in my future with clown puke gravel, a clam that opens and closes with water, a diver, Sponge Bob pineapple, a ship broken in half, a "No Fishing" sign.....hmmm what else?
