3 weeks ago I got a baby silver aro, it was about 3" when I got it and it has grown maybe half an inch in this time, I think this is because it's in a 15 gal to try and grow it out a bit incase my 7 - 8" Oscar eats it. My Oscar has never had feeders before and the aro looks just small enough to be eaten if he really wanted to.. Worth the risk? Hate to think I could be stunting him just now!
Will my Oscar eat it?

No. From 3.00 to 3.50 inches in 3 weeks is a 5.3% growth per week, which perhaps could be a little faster, but not necessarily. Over 3 months, that rate will take it from 3 to 6", over 5 months to 9". Of course each species grows differently when small, and even some fish will grow differently within the same species.
It should keep growing, but the tank and it's water quality may begin to limit it.
I had read that they grow extremely fast when young,as much as 2" per month so this seems slow, but I suppose the tank could be coming into play, even though i'm already doing three 40% water changes per week (not because of nitrates, just makes me feel better). I'll wait unti he's a bit thicker before adding him to the tank with the Oscar, thanks.
The Oscar will swallow the baby arowana.............The arownan's body is flexible and will bend accordinally to the mouth of the oscar..........The oscar's suction is powerful...........
