It is labeled as an advanced fish on their website. It is very common for online retailers not to guarentee a fish that they consider for the advanced aquarist. Even LiveAquaria does this. SWF has three regals on their site. The small & medium are no guarentee but the (more expensive) larger one is covered.
From their website:
This item is Not Guaranteed (NG), because either its behavior is irregular during acclimation, or because it is packed in a non-traditional way; in either case the hobbyist may not be familiar with the animals's true actual health and vitality because they are not familiar with its behavior. One can have every confidence when ordering this item, but it will not be covered under the guarantee because its natural behavior or how it is shipped differs from other items.
