HCA: Hermit Crab Association

My sister has a hermit crab in a 10 gallon and doesn't feed it or give it water or anything I keep telling her to, but she won't listen. So, when she is not looking, I feed it and give it the proper care. Of course it doesn't have a heater. She got it at a boardwalk in August, and the little guy is still fighting! I don't know what to do with it! I asked my sister to give it to my LFS, she said it's hers and she "loves it". I honestly don't know what to do. I tried so hard, but she won't listen... I think one day when I go to my LFS, I will sneak the hermit crab in and give it to the owner... their hermit crabs are really well taken care of. What can I do to help him? (It doesn't have a heater or a light)

Hello!The light is not essential, but heat (especially during the winter) is very important. Why not give her a heater, some good quality hermit crab food, and a hermit crab care book for Christmas? That will have her caring for the poor guy instead of you

If she isn't even trying to feed it then she doesn't love it. I think I would remove the crab and take it to them if they want it. And if or when she notices its gone tell her it must have escaped or died and you disposed of it. You may need to come up with a "How did it escape?" answer though.
