I'm hoping to just go off pellets as it's more convenient and can be automated. One of my favorites being Sustainable Aquatics Hatchery Diet. TDO also but not sure if that can be placed in an auto feeder as I keep mine refrigerated and Hikari has different blends. Key I believe is to keep it suspended long enough for it to soften for those picky eaters but as with anything experimenting to see what works and has the proper nutritional profile helps although I still feed frozen occasionally.
