My best guess is probably Fthaggua, the King Regent of the Fire Vampires from Donald Wandrei's "the Fire Vampires" (written in 1933).

Fthaggua is a Great Priest of Cthugha and also potentially its offspring, and appears as a "great flickering ball of cold, blue flame". It lives within the blue comet "Ktynga" that it steers around the cosmos, which is supposed to pass by Earth in the distant future (300 years from now). Fthaggua is surrounded by its vampiric subjects that appear as "electrical discharges of bright crimson" that "swim around their lord" (the flame vampires, which may be the inspiration for the blue-fire-fish). They feast on the life energy of sentient creatures, causing them to burst into flame during the process, and steal their memories which they store in Fthuggua's gestalt consciousness. It then uses these collective memories to better plan attacks on other sentient races, as its primary purpose is to travel the cosmos and feed.

If that sounds an awful lot like the modus operandi of the Umbral Star, then you wouldn't be wrong.
