I have two, one is skittish, the other could care less. When I vaccum the tank right beside the one, he wont move and I have to push him with the end to vaccum where he is. the other one avoids me at all costs. Good thing his snout is curved downward. The water flow over his crooked snout forces his head down when he swims fast. Kinda funny but sad. His head gets pushed through the gravel when he swims like that. Slows him down before he hits the side of the tank. Stotty my hybrid and planiceps were a little skittish when i set up my pond in my garage when I moved, but I put some long fake plants held down by huge rocks and they seem fine now, they each have their own plant to hide under. you could put an awning or something over your pond for when you turn on the lights or a dimmer. Just a thought.
