How about farlowella? IT can take time to them to reach maturity and to keep them alive they need LOTS of algae and you wouldn't have trouble selling them. You could also try laser, albino sterbai or Agassizii corys.
Get your feet wet first. Believe it or not I have never really bred any fish, just shrimp. I never really kept species that bred well in my setups without intervention. Start small and go from thereThanks for all the info! I agree, I should get my feet wet first. The only thing that I’ve had breed is my julies like 2 weeks ago. I like peppered more than bronze so I might do peppered. I was looking for a challenge but I tho k your right I should start small and work my way up pretty much
Sound food. They should be easy to sell. Just be aware that you wont make much money.Yeah I have an idea with a planted 29g and breeding peppered Cory cats. Sound good?
