When my bearded dragon was younger, he didn't react to his reflection. Because he didn't react, I figured that he either couldn't see it, or wasn't bothered by it. But now that he's fully grown, he's begun getting territorial and started acting out against this perceived threat that is his reflection in his terrarium glass.
As cute as it is to see him bobbing his head sometimes, I'm worried about the stress that it's causing him to see his reflection all the time. Especially since there are moments when he'll charge at it.
Is there anything I can do to either make the glass less reflective, or to make him not notice his reflection? The problem is that I don't want to cover the front of the glass, because then I wouldn't be able to see him.
For reference:
40 gallon (150 L) breeder tank.
24" ReptiSun 10.0 UV light.
150 watt ceramic lamp (keeps the basking area at 100 °F / 38 °C).
Slate tiles for substrate.
