Ok this is kinda strange so I figured I better ask.
Sometimes recently when momo comes up for air her nose whistles. It's not all the time, I'm thinking it's more when he is worn out from swimming or chasing a fish.
She isn't swimming sideways or anything like that and is eating and everything.
And she did have a strange nose since I got her so maybe it's just another defect.
Thanks for any advice.
