i have an oscar in a 350 gallon pond i thought it was 300 i guess its 350 anyway he only eats the goldfish and minnnows and feeder fish, same with the gar and the arrawanna??? THE MAN AT HTE LFS showed me which to pick out so i got rainbows and monos and african mbunas but why do they not eat the other small rainbows? Small monos? Small silver dollars? I know they cannt catch a giant danio.

Predatory fish like to hunt there attracted to panicking fish that dart around. Your Rainbows and Monos don't act like small gold fish do. There more calm and and don't attract the attention. But I would not say they will never eat them. If there small enough one day when you hadn't had time to get some feeders a Rainbow might all sudden go missing!
