The following plants look similar and may be confused:

Pinstripe Calathea Calathea ornata

Visually similar due to striped foliage, differing by thinner pale pink/white stripes vs. the broader red veins of Red Veined Prayer, and is also non-toxic

Chinese Evergreen Aglaonema commutatum

May be confused for its elongated patterned leaves, but has thicker glossier foliage and is toxic to pets due to calcium oxalate crystal content
