Help! My betta won't eat :( I bought him from petco about a week ago. He's a black double male tail betta his name is Tim Burton. He's in a 2.5 gal and I've tried giving him bloodworms (freeze dried), pellets, and flakes (wrong flakes so I tossed it) I've changed the water twice 100% water change because I don't understand the other ways. He's swimming around and he looks fine but he just is not interested in the food. I also ordered a heater and it should be arriving around June 4. Hopefully it's just the temperature that's bothering him. I'm so confused and I don't know what to do to get him to eat. Any help is greatly appreciated! Thanks!
