Super angry just isn't something I experience ... most Fish I know swim away long before.
Some people (like the Scorps you talked about), and many others .. hold a lot of things inside to let it fester. Most Pisces people don't do this ... they let thier irritation and frustrations out so that they don't get to a boiling point.
We can, and often do, get pissy/bithcy ... and when we do this, we're venting off so full rage doesn't ensue.
