What is the orientation of a fish when swimming?

Most fish have morphology that when oriented in a “normal” swimming position, they have a top (dorsal) side, a bottom (ventral) side, a front (anterior) side and a back (posterior) side. By this design we can see that the animal is designed to move primarily to the front and in most cases the front points to the horizontal direction you mentioned.

Do fish swim in the same direction when they mate?

Many species swim toward the surface during mating although they are facing in a horizontal direction while doing this. If you observe a school of fish you will often observe many of them swimming in every possible direction at one point or another, especially if you study smaller baitfish in a bait ball.
