My normal female always hides. I've had her for roughly a month now. She's always eaten well, pooped, and in general, hasn't had any problems. However, I performed my first complete cleaning of the tank just two days ago. It is completely rinsed of all cleaning agents. After reintroducing her into the now clean tank, she didn't go straight into the hide, which I expected. (She has always been curious. So much as shifting her water bowl causes her to investigate for a good 20 minutes), but the next day, I find her on top of her hide rather than in it. I'm staying at my Dad's until Friday, so I won't be able to update anyone on her status until then. If someone could just inform me on what the problem might be, (or if there is a problem at all) I would greatly appreciate it.
