Thank you moire and Kerie for identifying the cavies. I knew they were something special when I happened past the crabitat at the pet store and saw them. I just wasn't sure how special. Although I wasn't there to get more hermit crabs, I just had to bring them home. Now I hope I can provide good care for them. I am naming them Indigo and Jawa. They are both down to the bottom of the tank under the EE. I have left them completely alone and take a peek at the bottom of the iso tank to see if they're still okay (signs of movement, no dropped legs, no funny odors, etc.) They ate and drank the first night and have been down under the EE since. Now, of course, I worry about them, especially since I can't see them! They have food, water, humidity at 75% and temp at 78 degrees. Do I want to keep the humidity any higher? Any particular suggestions on the care of a cavipe? Poor Bob, all alone topside in the other tank, up after his molt with lots of energy, looking for his tanks mates, and everyone else snuggled down to the glass in various stages of molts. Now it's time to get my pacing slippers out! Thanks for "listening" as I wait and worry about all the molters, and the new babies.
