Hi Folks, I just set up a discus tank...a new adventure...but i kinda went into this blind. I know how to keep discus...but it was not was I was intending to do from the start. One question that I have is that I have purchased a couple bunches of cardamine from the pet shop and it seems to be melting completely! Is this becuase of the warm water in the discus tank??? Everything else seems to be doing ok..except the cardamine :( Any thoughts?????
