[Shadow~Fox]

I have show guppies that I want to develop. Any links on how to do it? I want to increase their fin size and their colours.

Feed Newly Hatched Brine shrimp 3 time a day and do plenty of water changes, Give the fish plenty of space, Remove males into a spertate tank and grow on their own.

Resualts will be good sized quality fish
