The thought of breeding fish for profit crosses my mind every now and then, gets me thinking as to how I'd approach this endeavour. And it's something I've been taking half seriously, breeding fish for profit would be way more interesting than getting a casual job at Macca's or Woolies.
Garden variety livebearers such as guppies and mollies are boring, and not exactly uncommon, also already very cheap at various LFS and pet stores, which is why I wouldn't be breeding them.
So it's got me wondering if I were to start a small business selling fish, what's in high demand right now? Natives (not Aussie natives but like local natives; pygmy perch, western galaxias, galaxiella Munda, galaxiella nigrostriata, bostockia porosa) are my specialty (plus they aren't common in the marketplace) but I don't know if a ton of people are interested in them?
