Our third Lou Han fish. He was acquired to replace Ah Hei and also to keep Ah Han company. He is named Ah Zhi due to his purple hue colour under the light. Hence the name Ah Zhi (purple in Chinese). He is the most naughty of the 3, biting anything we threw into the water, even the tube when pumping water out. Besides, he also constantly jump out of the water, knocking the tank cover over once.
