I have been having a problem with my crypts. I believe the species is Spiralis it can be seen in my album picture the tall crypt in the back right corner. It keeps loosing it's leaves and used to be so pretty as seen in the picture. It only has about 2 leaves now and they keep dying. I took it out and tried floating it in my shrimp tank giving it more light and a good cleaning. Now that the roots are exposed I can see what looks like a Rhizome on a anubius. Do cypts actually have rhizome's and am I killing it by burrying the rhizome. How do you plant crypts? Rhizome above substrate or is it not really a rhizome and can be burried?
