I currently have a pair of Angelfish, they recently laid eggs which I did not give any attention to, its been 2 weeks now and I can see that the fry had gotten larger.... I'm not sure if I'm overfeeding them with Daphnia because the fry can eat it and at the same time the parents does...But that's not my question...

My question is can I keep them with their parents forever? Well not really forever only until they grow the size of a quarter....is that possible?
