Krib loneliness

So I noticed my papa krib (who spends his entire life hidden in his cave) was thoroughly emaciated tonight. And mama krib hasn't been happy for ages either, and also looked a bit thin. So I decided to move mama into the big tank with papa. Papa's still in his cave. Mama was even in there with him for a while, but she's out again at the moment. Hope they both do ok.
