I still havent evolve them yet... got over 200 candies each for the commons like pidgeys, caterpies, widget and the other pokemons. Like I say waiting for the right time. I can get like 10-15 magikcarp per day, I dont have the patience to sit and wait for them to respawn at their nest cause I always see a squirtle nearby and go hunting for it but cant seem to find it. The squirtle seems to respawn every 30-60 min
