Tarot Teachings. In particular, I like the ideas that fish represent emotion/intuition because they 'move and react according to intuitive instinct', and 'abide by the flow, move with the current, accepting the yawning void in which they live.'
The Cups suit in the Tarot Illuminati features faery-like folk with silver hair and pale skin, as opposed to the other courts(Wands - Persia, Swords - Elizabethan England, Pentacles - Asia). I think this is probably because the Cups suit concerns itself with the intuition and that part of the self that is more fanciful and nebulous.
Overall I'd say the card is suggesting to me that I be sensitive to things today, both to my own emotions and those of others. I need to pay particular attention to the ebb flow of my own inner world. Perhaps some new insight will pop up, like a fish emerging from a cup.
