ive been a fish owner, for many years but never have tried breeding. i have alot of 5, 10, and 20 gallon tanks lying around as well filters, decor, the vast majority of the needed stuff for setting up extra tanks, my question is what should i try, something easy and relativly cheep and quick to start up (ive heard of people paying $500 + for breeding pairs) im not looking to pull a profit but it would be nice to raise something that i could sell / give away so im not stuck with a ton of extra fish. any ideas or input would be great, thanks.
