sexing Native fish?

Recommended Posts

If I am not mistaken quite a few of the large native perciformes start out male and change to female when they get bigger .

I don't know which one do and which ones don't - you would be best to pm one of the ANGFA guys on here .

Tandanus (Eel tail catfish) should be able to be vented .

Neither the Percichthyid the Bass or the Terapontid the Barcoo are protandrous need to canulate them to sex them.

The Tandanus can be sexed as can all Plotisids, male has a long cylindrical papilla, female an obvious triangular urinogenital papilla
