Sparkly shiny Pokemon

[Berry]

Got a shiny Magikarp and a normal Magikarp by accidentally breeding two of my Gyarados(Ridley and Ole Missus) when i put it in the day care.

Gonna put a screenshot right here:

Also on a side note:

My second was more interesting: I had been looking for feebas in Diamond version, fishing along the shoreline for 4 hours, I then realized I could fish while surfing, surfed out to the middle of the pond, went fishing and the first pokemon that appeared was a shiny magikarp.

Is this a coincidence?Or something much bigger?
