Normal
Mine had a really long permolt fasting phase (+/- 6 months). A few weeks before the molt, she would wander between her hide and the corner she ended up molting in, she also became quite sluggish. Mine never had a proper bald spot (how I can tell when my B. Boehmei is ready to flip over) or got considerably fatter like my LP, GBB and A. Geniculata, but looked greyer/duller than normal (she's quite red and pink usually).
