Before anyone judges, I have been keeping and breeding tropical fish for 12 years plus but have only bred things like guppies and bristle nose plecs and sold them/given them away. I am contemplating breeding fish on a bigger scale and one particular species, I'm not bothered if I make hardly any money out of it but would like to think I could make a little bit out of my hobby. I have done quite a bit of research and I know that breeding takes up a lot of space and time and I might not be that successful. Has anyone else breed fish on a bigger scale and sold them online or too fish shops?
