Aquariums and Fish Keeping

This is the 3rd betta I've had and he's just not food motivated like every other betta I've seen. We've tried pellets, flakes, and assorted freeze dried shit and he'll still mostly ignore it until it sinks to the bottom, and then maybe he'll nibble it. Bruh you are not a catfish or pleco, wtf. He's a "samurai" plakat male, while before I had the bog standard veiltails. Is this why he's weird? It doesn't seem likely tho?
