So my ghosts only went from L4 to L5 like 3 weeks ago and tonight 2 of them already molted again and are now L6's.. I read it usually takes about 5 weeks at least, so is this behavior normal? I keep them in a large terrarium where they can move around a lot with humidity about 70-80% and a temperature of 22-24 degrees celsius. They seem to be fine but, just like last time, they don't want to eat just yet. I'm always terrified they'll starve to death
