Re: plants in your setup?
Whenever I put live plants in my setup, my northern (or my ONLY dbt) pulls them out. Actually, I am convinced that she rearranges her setup at night as I can hear her moving her furniture, kitchen, etc. I repositioned the plants in the gravel and she will, inevitably, pull them out again and then push the gravel to one side of the tank. She has issues. I now leave anacharis in there- free floating. It isn’t the most pretty setup, but she can rearrange or eat as she pleases.
