I have a 20 gallon aquarium where I raise all the fry that I get. Right now I have over 200 guppy, molly, and platy fry. I have some that are growing at a rapid pace especially some of my sunset mollies that were born two weeks ago. My platies are also some that are growing fast, I have been seeing what colors and patterns they are going to be. I have several wagtails(red, yellow, silver) and I think one is going to be a Coral platy which are beautiful. Oh I forgot I have one white mickey mouse platy and several black mollies that I put in my main tank with the adults about a week ago and I see that they are getting slightly bigger. Trial and error is the name of the game here. I have had about one fry per day die besides those I find in there that are developed wrong, "I feed them to my tetras and tiger barbs!" I am thinking about selling mine too and I have a close friend that owns a LFS so I should get something out of it. Maybe the money that I have paid in buying all these fish due to trial and error on breeding which is close to about $200 on fish alone in the past four months!
