Sleeping In The Open

[nbxvgauq]

Hey guys. So as those of you on the Help forums know, I just lost a frog to MBD last week. I know it's not contagious, but for the past 3 days now my female has been acting somewhat differently: she sleeps out in the open every day. When I had the male, they would both hide in different spots throughout the tank, but almost always together, so that it was almost impossible to find them. Now that the male is gone, the female sleeps right up in front of the glass doors.

Her appetite is good and she is very active. Aside from this irregularity, she appears to be the same at night. The only other difference is in her coloring. She used to always be brown during the day and bright blue-green at night. Now she appears to stay blue-green throughout most of the day and night with no color changes.

Any ideas if I should be worried? Maybe I'm just being paranoid because of last week's incident...
