When considering tank shape for active swordtails, what configuration is often better suited to their swimming behavior?

Answer

A shallow, long tank

Swordtails benefit immensely from the surface area across the tank's length because they are constantly on the move; therefore, a shallow, long tank is often better suited to their active behavior than a tall, narrow one of the same volume.
