I have always been interested in breeding fish but I have always stuck to the easy ones to breed, livebearers. I am going to set my 10 gallon back up this weekend and am moving some of the fish out of my 29 gallon to the 10 gallon so this will free up some room for more fish in my 29 gallon. Like I said, I have always stuck with easy to sex, easy to breed livebearers (mollies, guppies, platies). I would really like to take on an egg-laying/scattering species but am looking for a species that is relatively easy to sex and then easy to breed. Does anybody have any suggestions?
