My 11 inch female jag is very peaceful with her tankmates for the most part. My festae, FH, and my JD all are dominant over her. That is unless I turn the lights of the tank off and there is another small light such as sunrise, or the TV on. If it is totally dark, or just during the day with the lights off, she is fine. Once it is dark outside and there is a little light, she goes crazy. My festae, and FH still win, but she starts attacking everyone in the morning for about 30 minutes at sunrise, and if I have all the light off at night and am watching TV. What is up? Anyone experience this?
