In fantasy, we use a lot of dragons.
In more liberal fantasy, we use a lot of different things and call them dragons.
I've recently uploaded an image (post #859575) of a character original to me who, within the context of my work, is considered a dragon. Specifically, her exact species is named as wishdragon.
However, that is, to my knowledge, currently the only image in the universe including such a wishdragon, and the image already has her similarly-exclusive character name (rhubarb), so I did not include the tag for practical reasons.
At what point (number of images, supporting documentation, etc.) would it be considered acceptable to add the wishdragon tag and set it to a formal species tag?
