1.购买鱼儿的总数必须为单数。 2.一缸鱼中一定要穿插一尾深黑色的鱼类，才有稳定、镇厄效果，否则虽然发了财，未必留得住。 3.一般办公室的财位是在出入门口的对角位置，而其财位适合置鱼缸。且绝不能放置杂物，或任由墙角、地板剥裂。另切忌勿摆在宅心。

4.钱财与富裕属东南方，事业成功则属北方，故可将鱼缸置于东南方或北方。5.北方在五行中属水，喜用色是黑、蓝色。故如在北方放置鱼缸可与蓝色丝织品搭配。

6.东南方在五行中属木，喜用色是绿色。而且水生木，故在东南方配合鱼缸摆设圆叶的绿色植物，可有不错的效果。

7.切勿在鱼缸旁摆设属五行相克(火、土)器具及方位相克之颜色物品。

8.鱼缸摆设地点需远离窗户等阳光可直接照射的地方，以阴暗处为原则。

9.如鱼缸挨着墙壁，墙上可以挂上瀑布、大海之类的照片。象征财源生生不息，不易计量。
