Glofish are patented not copyrighted. Just like you patent a machine. Intentional breeding is illegal. The "and/or" is the key in item 4 below.

Intentional breeding of GloFish is prohibited due to license restrictions. It is made more difficult by hyperbaric treatment of the young to render them sterile.
