I woke up this morning to find my hermit sitting on a top rock not moving at all, he is hanging part way out of his shell but not moving. Is this normal? I thought he may be dead so I checked my params, ammonia 0 nitrite 0 nitrate 5. After checking these I figured I should pull him but as soon as my hand got close to him he jerked halfway back into his shell. After about 2 hours he is sitting there lifeless again. I'll try getting a pic. Is it possible he is about to molt? Ive had him about 3 weeks with no issue
