When I had Oscars and Cichlids I bred swordtails, mollies and platies, about 3 of each in a 30 gallon by theirselves, I let them do their thing, majority of the babies were eaten by the parents or other fish, then I would take some out to feed the others, I think I had 5 or 6 babies become adults that I rehomed..... but I was just letting who ever survived survive, they ended up being beautiful and I scrapped the project shortly after due to the time of year (ice was causing constant electrical failures, I ended up loosing one of my oscars and both of my cichlids from power failures) def. worth doing, cheap, fun, and they enjoyed it (though since my fish were larger than bettas I still had to suplement feeder fish for the oscars and both with pellets)
