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.
