So I have had a Bimac from TomH for over a month now, it was doing great, exploring the aquarium all the time, playing with rocks and seashells, hunting the little damselfish I had in the tank, but 4 days ago it stopped leaving it's den, I thought it might be the alkalinity, since it was a little low, but it's been back to 170 mg/L for over a day now and she still isn't coming out of her den, she didn't even eat yesterday's shrimp. I don't think that she has layed eggs, I don't see any and I just got her so she shouldn't be that old. She isn't weak or anything either, when I tried to remove shells to see what was going on, she grabbed my fingers and started pulling them with her very hard and she wouldn't let me move the shells, holding on to them with a lot of force. What could I be doing wrong?
Also, I don't know why the image is reversed.
