To capitalize or not capitalize? (Race Names)

[Naruzeldamaster]

So I've been going back and forth on this while writing in most of my current projects.
I am undecided if I should always capitalize the first letter of each word in a race/creature name or not.
I'm torn on both because I use the names in different contexts all the time in one of my stories.
Two of the stories are fanfiction and in most cases the races are capitalized but when they're used in 'regular' conversation they aren't.
Same with my own fictional races.

If I were to write an animal fantasy, I would not have Mice and Elephants and Dogs. All would be lower case. That's my logic for writing a "human" fantasy, if you please. I have elves, dwarves, gnomes, ogres, orcs, trolls ... and humans. So far, that seems to work fine.

But as you've observed, in certain micro-genres, there are conventions to be respected.
