I have a 5" aggressive jag cichlid. He is just a bully. He is beautiful though so I'd like to keep him. Tomorrow I am getting a jardini arowana and wanted to assure that I don't get him beat up or stressed out. I was thinking about putting the jag in a 5 gallon bucket with a air sponge filter.(that already has good bacteria in it so I don't have to worry about ammonia). I was going to wait about 2 or 3 days before re introduce the jag. Please let me know is this is a good or bad idea and if you have any better ones, I am open. I have a grow out tank but the tank is full of Texas cichlids that the jag would devour in 20 minutes. Please let me know your thoughts thanks
