Giant Danio Sexing Question

[mos119]

How do I tell if it's a male or female. All the descriptions I see online are very subjective. Is there anything in particular I can look for???

[Crepe]

No not really, to my understanding, in breeding conditions male danios develop small white protrusions on the underside of their mouths. So watch closely for that.

Really? That's wierd. I have a giant danio and he got a white thing on the bottom of his mouth. I though he had cut it on a piece of drift wood or something, though. It's a normal thing then?
