Hi Johnny. I think it's a great idea to keep the ratio of females way higher than that of males, as what you're doing. Buuuuut, as Amanda is saying, you'll be swomped with fry soon. Ah well, then you can come to the conclusion that you need to separate the males and the females, get yourself another tank (we all have Multiple Tank Syndrome here!

) and have a male tank and a female tank. If you decide to do that, make sure you have plenty of males or they get pretty aggressive to each other.
The problems with lots of babies are tank pollution (your water becomes toxic if you're overpopulated and don't keep up to a gruelling cleaning routine), and inbreeding (once the babies grow up, they will breed with their parents, giving rise to all sorts of genetic weaknesses and a very poor bloodline).
