I recently ordered 2 longfin Oscars from my LFS, so far I've fed them bloodworms, and guppy's (home bred). they are around 4 inches and very active. I did some dabbling in research for how often your supposed to feed them and whatnot, but I'd rather get information from actual fish hobbyists. my question/s is how often and what's the best food to feed these guys/girls for optimal growth? id rather pay the money for the fish's health and happiness.
