hybrid fry question

[mattster]

im new to the forum and not an expert in any way to raising tropical fish, i have a community 100 gallon tank, i purchased a "polar blue parrot" and right after i introduced it (wasnt sure of its sex) to the tank, my convict showed interest, not long afterwards i noticed they were together alot and had quite a few fry. i didnt want to loose the fry so i set up my 10 gallon hospital tank as a nursery and put half of them in. heres the question, its been about 2 weeks, and the fry in the 100 gallon are growing quicker than the ones in the 10 gallon. just curious why that would be. i feed them both the same, ground up pellets and dried beef heart.

Are the fry in the 100 gal. still with the parents? If so, they will grow quicker then fry that have been removed from their parents.
