Concerned about a female

[AjBalls]

Question though, she is only 90 grams at 6 - 8 months of age?

Yeah. Slow grower. Her sibling is over twice her size.

I had a similar situation with a female pastel last year. Barely 200 grams at a year old. When one I hatched a month later skyrocketed to 600 grams within 8 months.
