Also unassuming, the Pisces zodiac signs and meanings deal with acquiring vast amounts of knowledge, but you would never know it. They keep an extremely low profile compared to others in the zodiac. They are honest, unselfish, trustworthy and often have quiet dispositions. They can be overcautious and sometimes gullible. These qualities can cause the Pisces to be taken advantage of, which is unfortunate as this sign is beautifully gentle, and generous.
