I looked for a tread. So explain the character of your arowana. Some have different personalitys then others. My Silver arow is very skiddish. He's only 4 maybe 5 inches and i want him to get used to tank mates(moving into a 225 gallon in a month) and have 6 inch oscar really mellow(who dosnt bother him) and 3 spotted catfishes all 6-7 inches each and their all in a 150 gallon. Maybe when hes the monster of the tank he'll relize he can come out of the closet. If a fish swims below him he jumps and when the catfishes and Oscar eat he stays back so i feed him in the corner. So whats your Arowans character?
