anyone ever tried feeding the aro live grey prawns?those u get from fishing shops. i heard its good and the excitement for feeding is there.the live saltwater prawn is able to withstand freshwater for at least 1-2 hours before it dies. the arowana will just grab it and fight it to swallow it down.of cos u have to remove the spike at the prawn's head first and also the tail. the carotene comes from the prawn's shell.i know of a guy who fed his red aro that for 6 months and the aro grew from 12 inch to 20 inch in 6 mths.no kidding,in a 6ft tank.so the aro have to eat the shell together too for it to enhance colour,thats why i dun believe in those hikari pellets or aro pellets,i believe in real live food.
