OFFLINE

I am finding it impossible to move decorations in my first tank as the fish seem to think where ever my cursor is that's where they should go. It would be incredibly helpful if you had a button to hide the fish until the task of moving things around in the tank is completed.
I go from frustrated to irritated, to angry before I finally have to give up on moving things in my first tank and I don't want to have to sell the fish in that tank as it's my favorites aquarium.
If there is some other way besides reducing my fish number please tell me. I'm desperate.
