So for the last day or so more often than not whenever my beardie is in his tank while sitting on his log his mouth is kind of open maybe 1/4 the way... Is this normal? Is he mad? I did recently change him from a 20gal long tank to the crossfire set up.... using Reptasun bulb basking area is like 112 F and he is about 2 and half months old..... any suggestions?
