Hmmm

Hmmmm... I noticed today that You Betas head has become like almost a tanish color and his body has stayed black.

Sometimes their colors change as they get older or with the different types of foods that are offered.

Maybe the food because I just started them on a new type of pellet

Iv'e noticed this as well, older betta fish seem to darken up around the head with age, completely normal.
