My guys eat bloodworms only all the time, but I give them vitamins as well. The pellets contain some vitamins but not a great amount of protein compared to the bloodworms. The optimum diet is to have them eat both the way you had him doing it. (WITH pea treats a couple times a week at least) BUT there are some stubborn little bettas who do not like the feel of pellets or the taste of them or just the idea of them. You will not change them, they make up their minds and that is that.
Since I spoil my little guys, they get what they want to eat and I drop a few drops of vitamins in and feel like they are well fed. They do okay and don't have to have the tantrums to get what they want.
