So I bought my first elephant ear betta, and let me say he is just beautiful. But for the first week and half he refused to eat. I tried 3 different types of food and I've never owned a betta fish that wasn't a pig. I finally got him to eat and I was so happy, but he will only eat blood worms. He turns his nose up to everything else. I heard because blood worms are really fatty and you should only give it to them as treats, but this is all he will eat. He doesn't even try the other food, he looks at it and then swims away. Other than his eating habits he seems like a happy, cocky little Betta. He has even tried picking a fight with my cats when they wanted to drink his water(thankfully my cats have no interest in him, only the water) So is it ok to keep to the blood worms or should I try something else?
