hi! i have i RES turtle in a 120 gallon tank. my turtle is rubbing is rubbing his hand to his eye every 2-3 minutes while basking from the past few days. any idea if i have to be concerned about this? he is also occasionally yawning while basking. i think he is feeling irritated in the facial area. i caught him today basking while dipping his head underwater and shaking his head while rubbing his face with his hands.
