I have 3 RBTA in my 120. Two larger around 5-6" sometime and a smaller around 3-4". I did a major rock rearrangement but left the Nems rocks where they were. But th seascap around them changed. Two receded and I built some burms above them which I have found lets them crawl out later when they are adjusted. But on is actually hanging upside down in a cave. Like if you ever saw when people take the rock out and hang the Nem over a water dish to detach it. This Nem is hanging upside down. The top mouth side is resting on the ground. It is stretched to about 3 inches and dangling. It doesn't look good. All three have run for cover after the rocks were moved but I have not seen on look like this. Any tips? Nothing else change besides the rocks. And I kept their rocks in the same place but moved those around them. I am not very concerned about two of them but the one hanging upside down worries me somewhat.
