yeah it's a tiger oscar - and well colored too.
that sounds like the best way to go. if the oscar doesn't get eaten in the next few weeks it will grow very fast. it's only a matter of time before he wants the tank all for himself.
i once had a 10" silver arowana and 5" tiger oscar in a 75gal. the arowana was always covered in cuts from jumping into the lid trying to ecape from the oscar. i was worried that the lights would get broken so i re-homed the arowana. he was not suited to a 75 gal tank anyway. but that's just my experience, it may work out ok for other people
You could put the arowana in the 125g and leave the Oscar in the 75g
