Rainbowfish picky eating habits beginning to tick me off.
I have 8 rainbows. I try feeding them spirulina flakes, reg flake food, and frozen blood worms and mysis shrimp. They pretty much take them in their mouths and spit it out. They barely eat any of it. I buy decent quality foods too like Hikari, Ocean Nutrition, and Omega One. Any advice? The fish will attack the food vigorously, but just spit it right back out. I have another tank with just Swordtails and they devour the same food like Pirahnas.
