It is advisable to have a bigger female than a male. Best have 2 females and 1 male. Motoro's sometimes breed already if they have a discsize of around 12 inch (1,5-2 years old). Size depends on waterquality and feeding.
Variation is important. I feed mine: mussels, squid, worms, shrimps, fishfilet form the supermarket (pangasius, tuna or salmon without additions) and Hakiri cichlid gold. Ocasionally I feed some feederfish, but most of the time my arowana is to fast and eats them all.
When the rays were young I fed them twice sometime three times a day (as much as they could eat in 5 minutes). Now they are larger I feed them once a day and sometimes I skip a day.
