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?
I used to feed mine frozen blood worms. To be fair I also had a couple of newts that ate them so I would break a frozen cube in half and feed them all in one go. It was easy enough to use tweezers to wiggle them around in the water. My Betta was way more likely to grab them if he thought they were live.
