Pleco's Nostril Flaps

[morgan]

Hi, I have seen this question asked elsewhere by someone else but it was not answered (perhaps nobody knows!). I have wondered myself what these flaps are for as they seem to be too far away from the nostrils to be of much use. If anyone knows the answer please tell! PS My Pleco is a Common.

I think that they are for " smelling" for food since they eat stuff on the bottom of the tank.

Thanks for the reply. I wondered what they are for as they seem too far away from the nostrils to stop water going in if that was their purpose.
