pony-tail Posted November 15, 2013 Report Share Posted November 15, 2013 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 .

Sclero p Posted November 17, 2013 Report Share Posted November 17, 2013 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 Link to comment Share on other sites More sharing options...
