I've only raised them indoors in aquariums but I've had great success in small aquariums, and I've had the most success in small containers with a single sponge filter on a very very low air flow. I feel the containers work the best because of the small area that you can concentrate food and make sure everyone is eating good. I will say that you have to be on top of your water changes using the smaller containers as the can foul up with uneaten food pretty quickly, I use a turkey baster to suck up uneaten food and water for the water change. Personally I've never used plants for my fry containers but I don't think it would hurt at all, although mosses might make it a little more challenging to suck up uneaten food as it would get caught up in the moss. For feeding I like to use serra micron for the first few days, then after day 3 I add a tiny amount of baby brine and watch to see if the babies can actually eat them and if they do I start adding them along with the serra micron. If they aren't able to eat them yet I just retry that process daily until they are able to eat them. Once on baby brine they will start growing very quickly(but make sure to keep feeding the powdered food also), and eventually they can start eating small pellet foods such as the Hikari gold bag from Japan. Personally I don't add them back with my adults until they are eating pellets but you might be able to add them sooner if you really needed to. For feeding regiment I like to do serra micron and a small amount of baby brine before I leave for work in the morning, and then serra micron and a larger amount of baby brine when I get home from work. On the weekends I try to do 3 feedings but that doesn't always happen haha. For how much to feed I would recommend adding food and then watching your fry eat for about 5 minutes and start basing how much you feed off of how much they can actively eat in that amount of time. I know it might seem like a generic answer but it really works if you take the time to do it, it's fun to watch, and you'll learn a lot but just sitting and watching your fish sometimes. Also add a heater if you can, even the small preset ones work well, a little heat goes long way for growth but I would recommend 78 degrees as I seem to get the fastest growth at that temp with this feeding schedule.
