My female jaguar is doing some weird stuff. She's about 5" and everytime i turn my lights off she goes nuts in one corner of my tank! In from of the vorner is the back wall of a log cave so no entrance and she either attacks the wall, or looks like shes trying to scratch against it but doesn't touch it so just the motion. and she constantly digs she picks up a bunch of gravel and swims to other side of the tank and spits it out. Then continues going nuts on the spot turning and flipping around quickly some times she even rolls. This has been happening very night for the past week or two and only when the light goes off and in the same spot everytime and erpeats everything. What could this mean? ill try to get a video in the coming nights
