After some hesitation, all of my fish have really taken to my Very Special Seafood Blend (translation: "Co-op Seafood Medley", raw and pureed). I did not, however, add any Nori to the mix. Do dwarf angels benefit from having algae (Nori, in this case) incorporated into their food? My angel has generally been unimpressed with Emerald Feast cubes and the Nori that I've offered it, and picks instead at my well-algaed tank as well as eating its mealtime portions.
