Astrological interpretations of the Bible sometimes attempt to link Jacob's sons to the zodiac, claiming that when Reuben is called "unstable as water" (Genesis 49:4), this corresponds to Aquarius. However, there is far more to Reuben's description that does not fit the sign, and one could just as easily associate "water" with other astrological signs, such as Cancer the Crab. The analogy is highly speculative and ignores the rest of the historical and biblical context.
