belle_foudre;3729918; said:coldwater fish, such as comets or rosy reds should NOT be fed to a oscar. Oscars are warm water fish, and they cant digest coldwater fish fat. They are used to very lean fish. I would avoid any store bought feeder fish, they usually carry nasty parasites.
If you want to feed your oscar live fish raise your own tropicals. Any fast reproduceing tropical will work, mollies, sword tails, guppies are all good choices. But grow them yourself, otherwise its just a matter of time before you end up with a nasty infection. If you want to be safe and keep it easy, terrestrial worms and insects make great alternatives for a live food source.
