What is the view on putting discus and arowana together? I have seen people do it and have heard different views. Discus are a pretty sensitive fish and I am not sure if it is great to put them with an aro. I am thinking of trying to do it, maybe with some wild discus.
They wouldn't have to be wilds, just large enough to hold their own. 4"+ would be good. At feeding time thaw out some frozen bloodworms and pour them in the tank so they go everywhere. This discus will pick away at them.
