"Gentleman" behavior

This is a common behavior that emerges from the ever-evolving Brains of simulated Bibites. While it is not 100% guaranteed to emerge in every world, it is still considered worthy enough to take note of.

Description
This behavior is best described as a way of avoiding the death of another Bibite when a Bibite is obstructed, and is the most altruistic behavior documented so far.

When a Bibite is obstructed by another Bibite it will slow down and wait for the other Bibite to continue swimming. some variations of this behavior have even shown the use of pheromones from the obstructed Bibite that signal the other to speed up.

The use of coloration can further evolve this behavior by distinguishing between friend and foe.

The consequence of this behavior is that if two Bibites manage to face each other, then they stay still until the other either manages to swim away or dies.

Reason behind its existence
Natural selection is obviously the most significant mechanism at hand, and is the driving force behind why this behavior emerges in the first place. This behavior emerges to raise the survival chances of all Bibites involved.

Bibites that run into other Bibites blindly also have a chance of killing their own offspring, thus the genes stub for this behavior will eventually emerge to reduce this chance; almost always without a regard of the world settings involved.
