My Eastern Water Dragons have been sitting in their water for about a week with their eyes closed. They haven't been eating or going to the bathroom much. They're getting kind of dark, but they lighten up when I take them out of water and try to get them to move around a bit. I fed them minnows for the first time before this started happening. I think they're having digesting problems. My Dragons are almost 2 and 1/2 years old.
