No, I do not think that is true. Freeze dried bloodworms are good for them, I compared the ingredients to the regular food and it was not unhealthy. It had less fat then the regular food and was high in protein. Bloodworms are pretty good for them.
I have been giving my bettas Omega One freeze dried bloodworms frequently (a very small piece everyday, but I don't do it couple times a week now) and they have been very healthy and happy. They love them! Just don't replace there regular food with it, and they are better as treats, that's why I quit giving one to them everyday. It's hard not to because they get so excited about it. lol
Half or less than half a bloodworm is better I think because there stomach is as big as there eyes. When I gave my female betta a whole small bloodworm for the first time, her stomach got pretty big after eating it and she wouldn't eat anything else after that till I noticed a pellet dissapeared at night and the next day. She loved it, it was just too big. lol
