thx a lot everyone
i have seen gars and arowanas in communities many times as long as you have a huge tank and the fish are of similar sizes there is a good chance it could work,atm they patrol the top of the tank together.
they eat fish,mussles,prawns,cockles,earthworms,shrimp and your right its not cheap.
i tried a different flash mode on my camera what do ya think?
i think it shows the arowanas colours quite well
my new pro3 has arrived ready for the new tank
