I'm going to try DIY fish food soon. I want to add more variety from stuff you'd have to get at an asian market. Does anyone have one they'd trust/recommend? (Preferably on the northeast side, but I'm willing to travel if necessary.) Any particular brands or products to recommend?

I'm wary of getting stuff from an unknown source... but it's the only way to get the variety I want.

I'll eat lukewarm sushi that's been sitting out at HEB, but my fish deserve better.
