hey everybody i bought an silver arowana about 3" or 4" in size a week ago. He's in his own 45 gallon tank for now(untill he grows lil' bigger). so i was just wondering that can i do a complete water change once in a month like i use to do in my flowerhorn tank. i heard they are super-sensitive towards drastic change in water condition. im seeking for some advice for someone who has or had silver arowana!!
