Anyone know of any good flake food that is good for fish without alot of filler? I'm feeding my fish tetramin flakes and my fish don't seem to hot about it. Nobody likes the red flakes in it, seen all my fishes spit it out. I have cardinals, danios, cories, yoyo loach and an Eba. Also is there any significant difference with frozen food brands? Im using San Fran bay bloodworms and brine shrimp w/spirilina, just wondering if there is anything better for my fish.
