Oh, but Colin I'm totally aware of that. But even with the breeding forms of the big 4 there are differences in needs. That's also a fact. So, I do have to say that there's still a "but" in that story.The generalization about livebearers is due to most pet shops only selling common livebearers like guppies, mollies, swordtails and platies.
Hey, but I'm really glad that you're back. We've been missing you for a while...
