So I'm contemplating on starting up a tetra breeding project, and I want to know, what tetra would be the easiest to breed? I have a 5 gallon tank which I could use for breeding, and a 30 gallon tank that could be used to raise freshly bought fish to maturity (so conditioning), as well, I have walterworms to the fry/ to condition the adults, as well as frozen foods and various freeze-dried foods. I currently have rummynose and penguin tetras, but I've read they are difficult to breed, and I would like to start with something a lot easier. Any suggestions??
