For Feebas to evolve, you need to feed it Blue or Indigo Pokeblocks until you max out its Beauty rating (I know the Pamtre Berry is the best for this, but trust me, its a REAL biotch to grow enough for it to be used). I'm not sure what the other Berries are, but once you max-out your Feebas's Beauty, and just level it up and voila! Instant Milotic
