well when i got them they didnt have white heads, im guessing its like a morning face cuz they usualy have it when they just start to swim after they see some food on the top of the bowl, it darkens up as they flare... [for taidei]
on the other hand...
in this case my betta [slurpie] looks a bit too white, the head has no coloring of its own and he wont flare at his reflection or at my other betta when i remove towel from his bowl [treating fin rot, 80 degrees right?]
ps: slurpie hates bloodworms, frozen or freeze-dried, LOVES pellets and cucumbers does it have to do with nutrition or something?
oh yeah, he ignored his pellets today so i had to scoop it up before they sunk...
