I must have the world's pickiest betta! I've tried two kinds of pellets made for bettas, freeze dried bloodworms, frozen mysis shrimp, frozen reef caviar, and Ocean Nutrition instant baby brine shrimp (comes in a jar that looks like baby food, only smaller). He swims after the food as soon as I put it in like he's all excited and hungry. But then he will reluctantly take a bite, and promptly spit it back out! He will eventually eat pellets, but only after he's spit it out a few times. He apparently hates the instant baby brine shrimp. Just looks at it, doesn't seem to recognize its food at all. Anyone else tried it? He will also pick at algae wafers that I put in for the bottom feeders. But I don't think he's actually eating any of it. Is a picky betta common, and what did you guys do to acclimate them to new foods?
