I know this might be the wrong place to be but theres no where to put it. Yesterday I came back from the mall with 100-200 hermit crabs shells. I put 7-UP on my bed at 9:00 pm(iso was getting clean) thinking she would change her shell. She started to get into a shell the wrong way for first 3 minutes. Then she finally got out of her shell and went into the other shell. This was my first time and my heart was pounding. I put the other shell her size into the cage (maybe she doesn't like her shell or Waffles or Aqua want to change). So now I wake up wanting to see 7-UP and now as I pick her up I find... Aqua. Then I was shocked. Aqua change into another shell over night and it look like 7-UP shell but 7-UP is in the Coco-Hut.(so that was making the noise)! So now i'm typing away this thread at 7:30 am.
