How often do I feed my leachi?

As title reads.

All the people I asked have a different answer to the question and I'm confused af.

My leachi is 3+ months old and weighs 18gram.

I have been feeding him CGD every other day(10% of his weight) and he devours it in a few min.

Please enlighten me how often and how much(5% or 10% of his weight) I should feed him.

I really need a clear, straightforward and legit answer please!

Thank you.
