Which lungfish has the duckbill mouth?

[Samaka]

I have seen marbled lungfish on youtube with a big flattened and upturned mouth some people have called duckbilled mouth.

I'm not sure if this is what adults of some lungfish species normally end up looking like, or do their mouths grow like that from rubbing up against the glass?

I believe it is normal. They don't seem to rub on the glass. I have had two, and neither has had a sore on the snout from rubbing and they don't normally swim fast enough to damage the nose from ramming it.

Thanks for the message Rodge, glad you know what I meant by that. See you soon.
