Do you think 30 cm fish can be eaten by a full grown silver arowana? Maybe, maybe not. Depends on the arowana's personality, I guessed.

I have never had an arowana myself so i couldnt tell you for sure, personality definitely matters, size too, i believe if the arowana been in the tank with the fish from when its young/smaller it wont see it as food even when it grows a bit.

My hujeta gars have been eating Colombia tetra's wich are quite a lot smaller but when i introduced bleeding heart tetra's wich are now about half the size as the hujeta they were cool with eachother, now when the hujeta's have grown a bit and the bleeding hearts have not grown so much theyre still cool with eachother.

But they will need enough space and hiding spots just to be sure
