Hey everyone I'm adding on to my 30 gal. tank with a couple of Discus. This will be my first time. I'm currently testing the water and adding things to the water to make sure its right. If anyone has any suggestions or any personal experience that would be great. I'm a begginer when it comes to Discus, so I'll take all the help I can get. Also wondering if there is a difference between the kinds of Discus behaviorly? If true what should I get?
