First and foremost, please write in proper English. Do not use "2" for "to", "2day" for "today", etc. Terminate sentences with fullstop. Capitalize beginning of
sentences. You know the drill. It's very difficult reading your posts.
Now, to try answering your questions.
Pellets and green vegetables should be staple for turtles older than a year. Yours
is 3 years old, so he needs half headsize pellets daily and vegetables. It's quite
alright to overfeed a little on vegetables. Please start reading from
this page
regarding feeding. Dried krill is meant to be a treat, not a staple food.
Don't give up giving the proper diet for your turtle. Eventually, your turtle will
eat the staple food. Just keep trying.
It's normal for turtles to behave like what you describe as "tantrum". Usually,
it's a sign that the turtle is begging for food. We should not give in to that
begging. Once the turtle has eaten its portion of the day, it's good. Consider
the begging as exercise.
Turtle should not be handled much. I think you've done the right thing by
leaving your turtle alone most of the time in its tank.
I hope this helps. I'm sorry if it doesn't.
