20 L number Banana (k: 5) since 2009-06-18; who writes, "All my otos seem to breed but I never see it, there just appears to be more once in a while. I move the smallest ones to other tanks and wait for the next batch. Only thing that seems relevant is that they only breed in this tank with harder water. Update: Pretty sure these guys are the most prolific breeders. Most of the ones I give away are these ones."
