So I picked up a white Betta a few months ago an now he is more pink than white. My guess is that the food that I am feeding him (hakari betta bio-gold and NLS thera a) has a lot of color inhansers in it. Is there something that I can feed him that is still good for him but will bring out his white? Probably too late but had to ask.
Well you may have picked up a younger male, and he is turning pink because that may be his his natural color. Or you may be right about what your feeding him. If I were you, I'd feed your betta something like this (7 day diet):
Tip: Bettas can go on for a week without eating at all.
1st day: Tropical Flake
2nd day: Frozen meaty food, or live (Bloodworms, worms, etc)
3rd day: Tropical Flake
4th day: Spirulina Flake
5th day: Do not feed
6th day: Frozen Mosquito larva (Bettas readily eat mosquito larva. These insects are found in nature where bettas live - the rice paddies. Though it's not that easy to find mosquito larva in the Western world unless you have a tank to breed insects specifically to feed your betta)
7th day: Tropical Flake
This is just a general guideline (mine, lol)
When preparing them for spawning, more meaty foods are better. But for your problem (coloration) do more of the Spirulina flake. This should help the coloration get back to it's natural state as it's pretty neutral in color after ingested.
