I throw the greenfins in with the ones above, and then add all three fins of the beta ... twin, silky and green. Only three breedings to any fish using those. But to do it all in one breeding? That's beyond me. The way I breed the final three fish are breed from the third generation, so there wouldn't be any way to do it in one. ... It would be interesting, though, if there were some that could breed a whole batch with one crossing ... but you'd still have to find a way to get those.
