There is a Xaela tribe called the Ejinn that seems to be along what you want.
"A river tribe that chooses to swim from place to place rather than walk or take boats. It is said that members of the Ejinn can hold their breaths for up to a quarter bell, and will often migrate while almost completely submerged in order to avoid contact with hostile tribes."
That being said, I personally think the bio luminescence is a bit out there. Everything else seems fine. Alchemy might be a neat way to build on already present traits.
