Well sorry to break it to you but your doing it wrong.
First off your best to have a bare bottom aquarium because at night the guppies go to the bottom. Then the bacteria builds up in the substrate. When the guppies sleep the bacteria starts to eat there fins and its hard to grow back.
Second the fancy guppies you may get come from a sterile enviorment. A lot of breeders do water changes every 2 days. They bleach there tanks once a month. And that makes the guppy have no amune system. So they'll be very weak to sudden changes.
Also its alright but its better to breed guppies in a 20 gallon aquarium where the guppies are easy to catch when born and have a clean bottom. Its best to have they babies seperated for 3 months before adding them back to the parent aquarium b/c they are more fragile when young and deises can catch to them faster then the parents. This should be done with each batch but if you don't got the room its fine to keep with parents but be careful with them.
Next if you want to get java moss and cork and wrap it together with an elastic and it will stay on the top. Sponge filters should be ran on the parent tank and water should be changed by 10 % at least twice a week with water thats been conditioned and ran with an air stone for 8 - 12 hours.
After your guppies are born and are mature find the female with no color to it and keep it no matter what and that will be your "blonde" guppy. Then you get your nicest male and breed them and when they have babies they will look exactly like there father.
After 200 babies that are grown to maturity you got your good guppies. This is when you can guess the out comes. And you can sell them for good money.
Tip: Try to get Snakeskin guppies since there the hardiest of all fancy guppies and can be vauled at $150 +
Good luck and im just telling you the best way breeders do it and there your guppies so you can do whatever you like with them. If you got any questions feel free to pm me.
