Looks good so far. I do think the tail slap should be changed to a tail barb, with a note that it does piercing damage.
Doesn't seem like there are really any other special abilities to worry about, unless we want to spell out "immunity to gravity effects" a bit more.
We should probably spell it out. In fact, I think we've done it before for one of the other gravity-themed critters. I'll begin the search...
Hmmm, it does seem like that would be useful for him, wouldn't it. Maybe the difference is that he can alter gravity, but the ni'iath just seem to ignore it.

Indeed. We could always add it to him once we work up the ability if we think it's appropriate.
Anyway, I've had no luck finding the ability. Let's just whip something up:
Immunity to Gravity Effects (Ex?): A ni'iath is immune to any gravity-based effect (such as a reverse gravity spell). It can function in areas of light or heavy gravity as if it were in an area of normal gravity.
I don't like the last sentence, as it implies it is affected by normal gravity. The original text is very clear that they just don't feel gravity at all. How about this?
Immunity to Gravity Effects (Ex?): A ni'iath is immune to any gravity-based effect (such as a reverse gravity spell or falling damage). It maintains perfect flight and all abilities in light or heavy gravity as well as normal gravity.
