I just got a crab a couple of days ago. His name is cleets. He is the best. I'm buying him another one tomorrow so he's not so lonely. But thats not why I'm writing to you guys. The reason is that he seems unhappy. He hasn't eaten or drinkn from hat i know of. He is also not very active. And once he gave me a little pinch. Not piecing the skin but it did startle me. Its like he doesn't trust me. I feel bad for him. I have a little tank for him so i think either he is lonely or he needs a bigger tank. Please help me and Cleets.
