Moon fish were a species of fish that tooka cats could eat. Back in 230 BBY, Jedi Knight Yacek Sparkburn prepared moon fish at the Jedi temple located on the Outer Rim world of Dalna, subsequently putting it into a woven bag along with fruits and other things in separate bags. As Sparkburn, carrying the bags, got closer to a group within the temple, the tookas living there gathered around him, crying sadly, which made the Jedi laugh. Sparkburn then commented that the cats must have detected the aroma of the moon fish he was carrying, before introducing himself to Vernestra Rwoh, a fellow Jedi Knight, and her Padawan, Imri Cantaros.
The junior novel The High Republic: Mission to Disaster, which was released in 2022 and authored by Justina Ireland, mentioned moon fish; the novel was published as a component of Phase I of the Star Wars: The High Republic multimedia initiative.
