breeding age is about 1 1/2 years old or about 3 inch i have had mine breed smaller than that but its not common you need lots of cave or pvc 3/4, feed them lots of black worms 4 a week do a 50% water change to mimic the rainy season and watch the magic happen once the egg are laid the male will do the rest he will fan them and Gard them till they have hatch and the egg yoke has went away
