Drew a little extra of this adopt: http://www.furaffinity.net/view/16709743/ , and decided to took the opportunity to explain some things about this species (the owner of the adopt will get the full res of this extra without the text of course XD)
here is also a gif: http://orig15.deviantart.net/e6c7/f.....es-d8vp9ao.gif

so, well, basically their head and the thing in their tail are lanterns and these glow in the dark, they can also make these glow with more intensity whenever they want/need it, in some occasions the intensity of the glow can increase unintentionally, usually when they're angry/blushing

their arms can be made of clothe, paper or other materials but usually matching the lantern material

their heart is a flame and when they die this is extinguished...their hands are made of sparkles and their ears, head, tail lantern, and some body parts can produce sparkles as well, this is, like, a residual energy produced by the activity of their heart, indicating that it's still alive

they have the ability of controlling fire but this is relative to their size (which is really small) whereby they can only manipulate little flames and slight temperature fluctuations...they can also float

they don't talk and their size is about 8cm...they don't like the cold and they can feed on almost anything that can be consumed by fire

more info later!
