Dude i KNOW your new and all but I would only keep one pair of convicts and return the rest. Faster results my man less conpetition. Just wait and look at your LFS and pick a male with pointy fins and he will be larger then the rest and brightly colored. Also feed them black worm make one central hiding location and large water change ever two days. you will breed them in a month. Remember Just one terra cotta pot or cave. I was breeding these fish when I was 12. Beware you will have more babies than what you want. I hope you have something you want to feed them too.
