Incredibly, I thought my Cespitularia was dying. I pretty much gave up on it and considered it dead. I pulled most of it and left the other half just because I was too lazy to pull it out. Well, a few weeks later and it's back to normal
I still cant figure out how it survived and what caused the crash to begin with. I am guessing it was due to my new skimmer that pulled out a lot of the excess nutrients.
