My Russian Tortoise today, when I picked her up for a bit, let out quite a bit of mostly clear, potentially brown-ish fluid. I thought they didn't excrete liquids, so could this be a bigger problem? She's been with me about a week and a half, and eats only romaine leaves and dandelions. I've tried collards and something else, the name eludes me at the moment, if that lends a possible explanation. If that is most likely the problem, how do I get her to expand what she views as food?
