Are they commonly put in the same tank?

Warning, this video is of an arowana being fed a live mouse. I know a lot of people feel their fish live food, but some people may not want to see this.

Suprised the archer fish hasn't been eaten, doesn't look much bigger than the mouse!

I thought it mught have been a fly river turtle, but it just looks like a normal red ear one. I guess its too small to bother any of the fish.

I was watching this and other arowana videos last night on youtube came across the monster fish keepers one which was of a half doz red arowanas in a tank and they were dropping some live fish in man those small ones were jetting around all were eaten though was good fun for the arowanas i bet

I was suprised the turtle was still in there, cool tho
