I feed Blaze Hikari Betta Bio-Gold. So far I think that's the best food there is - not that I've tried all of them, but Blaze and any other betta I've ever had loves it. It hardly took him any time (like less than 4 minutes) to get used to it - and bettas are known for pickiness when it comes to food, so it's surprising that he took it that fast...what's more, I switched foods immediately instead of over a period of time (though over a period of time is better for them - if he'd shown signs of not liking it, I'd probably have done it slower) Anyways, that's the end of my advertisement for Hikari Betta Bio-Gold

They usually take it pretty immediately (the food).
