They eat what fit in their mouths....

Nocturnal fish are sutible with Oscars(ghost knife, pleco).

Larger fish are suitable (your Oscar will reach around 30cm so larger than that)

Most African ciclids are fine DO NOT MIX Malawi (eg choose jack dempsey, pacu, giant gourami, severums, parrot fish, birchir, fire eel, firemouth, eartheater/geophagus, girrafe, buffalo, paradise etc)

When introducing a new fish to an Oscar tank, rearrange the tank and do a large waterchange. this stops the Oscar attempting to protect its territory.

if the Oscar is much larger than say, the new Oscar or JD, remove the larger- rearrange tank- put new fish in for 2 days in with a blanket over tank then put big Oscar back in with covering on for a further 2 days. if this doesnt work it is likely you will need to grow the smaller Oscar out to a larger size first.

No more than 1 Oscar (exception a pair) req a 6x2x2 tank.
