I have a red ear slider. and i was wondering if it is normal for them to sometimes make a few bubbles through their nose/mouth. Cause sometimes when Ranger slides off of his basking rock and into the water a few bubbles come out of his nose or mouth. Same thing when he sticks his head out of the water to breathe and stick it back into the water.
He never makes bubbles while he is in the water and has not poked/got off of his basking rock.
So is this normal?
