Ahh... a difference of opinion. I don't really want to breed, and if I did get females I would let nature takes its course, as it were, if they did actually have babies. But I'm still curious - if the 1 gallon/inch of fish rule is bogus, how many fish can live in a 10 gallon tank before the biological filter would be overwhelmed?
It depends on the filter, the fish, the feeding...
