I feed live Microworms, Grindal worms and BBS, as well as Golden Pearls and Flake foods. They are voracious feeders and are super active, that way you know they are eating.. I have Black Neon Tetras and Black Emperor TETRAS, as well as any dozen or so Albino Coryadors and five Ottocats and a single Silvertip Pleco into my 45 gallon tank btw
