While we're playing that game, the observation his mouth is a shallow chamber without a passage to digestive organs suggests that he sucks at actually eating things, and his lack of a skeleton or musculature would mean he lacks the strength to pursue or overpower prey. Given these parameters, he likely feeds like a venus flytrap, trapping comparatively small prey between his jaws, secreting enzymes to digest it and absorbing nutrition via the mucosal lining.
Found a store that sells legitimate honey gouramis. Last ones I bought turned out to be thick lipped gouramis and they ended up going Highlander on each other and the remaining one jumped out of the aquarium last week. Real honeys are a lot more timid and less territorial so we'll see how that goes.
What I know about the film (besides Disney refusing to edit out their token 'look we support the gays please support us gays' scene) is that Buzz Lightyear is clearly meant to parody sci-fi stuff based on what you see of the 'lore' (as little of it as you see in the Toy Story films) but like Lightyear...plays it completely straight and serious.
They honestly should have just done a film version of the old Buzz Lightyear of Star Command and have it be a comedic sci-fi parody film like that series instead.
(Also regardless of his politics, Tim Allen is Buzz Lightyear as far as the majority of people are concerned so him not being in the movie makes it feel cheaper tbh.)
