I used the 'staggered' approach for my Oscar Brick.
6 small meals 2"- 4"
4 small meals 4" -7"
3 meals 8" -10"
2 meals 10" -12"
12" - now 1 meal a day. He's currently over 14".
He grew at a 2- 2.5 " clip a month till about 8 inches, then less.
Up until he was 2 years old he ate 90% Hikari pellets, all types. Started turning away from pellets as he approached a foot. Ate nightcrawlers for a couple of months then lost interest.
Now he's a insect eater. He loves his mix of crickets, shrimp, and mealworms. I dust them with reptile vitamin powder. He only eats about 10 percent pellets now.
