I noticed today that my bigger turtle is breathing with his mouth open underwater. I read a previous message about open mouth breathing and the author said it happened out of the water, well mine happens within. Does this mean he has a RI? I just got a new tank and he has been hiding out in the plants and now that he is breathing with his mouth open under water, i am concerned. He is eating well and i don't notice any unbalance swimming, then again, he's hiding out....he scurries when he swims but i thought that was normal vs a sign of being sick....comfused and a newbie!
thanks for your thoughts!
