A quick update. I cleaned out the tank really well yesterday but only did about 30% water change (because I've been told not to do the whole thing at once). It made a big difference. They are moving around a lot more and searching for food. Chip (the boy) shed finally and even peeled off his feet (which hung around a bit longer than the rest). Dale still looks a bit tattered, but she's actively swimming and is eating, going up for air and coming back down. No more hiding. She is also really obsessed with the box that has their bloodworm packets in it. I've moved the box to the other side of the tank (sits right next to their tank) and she's been hanging around that side now. I don't know if she knows the worms are in there or if she has a crush on the frog on the box.

Thank you for the suggestions. They do have a thermometer and a filter already. The aren't in their one gallon tank anymore (that was the previous owner) and I have been cleaning it. I obviously didn't do the best job last time, so I worked hard this time. I think it also just got too cold with the temp drop in the house. They are back up to around 75 right now and it's still getting warmer. I scrubbed all I could (without using soap, since I read that was a big fat no-no) and wiped a lot of algae off their silk plants and their little house. They really seem to be much better. I just wish Dale would finish peeling off.

Yes, they do eat some of their skin, but not all of it. Maybe I am over feeding. Thanks again for answering me and trying to help me. Hopefully I've done well enough to ensure her safety and health. I adore these little creatures and want them to be safe.
