Well, it’s happened, my crypt has melted for the first time. I had been warned that crypts are prone to that, but I thought I was going to be lucky since it didn’t melt after being transplanted into my tank.
I’m not 100% sure on why mine decided to melt. I know they will do it for any number of reasons like being moved, change in lighting, change in nutrients, change in temperature, etc etc.
However, I haven’t changed anything on my tank in about three weeks when I swapped over to my custom LED light fixture. That’s the only factor that I think would cause it to melt, but three weeks is a bit of a delayed reaction. Hopefully it will spring back to life after it’s done melting for whatever reason set it off.
