Richard Posted February 20, 2008 Share Posted February 20, 2008 Hey guys, I have found some juvies for sale nearby, they are roughly 7-8cm. I am looking at purchusing a pair but am unsure how to sex the females. Is there anything specific i need to look at? The only way i am able to sex them is by behaviour but just wondering if there is any anatomical techniques to sex them at that size. cheers, Richard.

poncho Posted February 20, 2008 Share Posted February 20, 2008 I would look at size as a rough guide, generally females will be perceivably smaller if you're looking hard enough. This has been what I have found with Lamprologus and Lepidiolamprologus species I have kept before. I haven't yet kept any tetracanthus though, so am just assuming this would apply to that particular species as well. Though using this method I don't think it would be wise to bet your house on being able to correctly sex the fish. Link to comment Share on other sites More sharing options...
fishdance Posted February 22, 2008 Share Posted February 22, 2008 It has been a while since I kept and bred these but I vaguely remember the caudal (tail) spots are different. Similar to Hypsophrys nicaraguensis. Regardless, even if you can reliably sex them, I would recommend you get more than just one of each sex although you may need to get rid of excess fish later.

Bruce Posted February 22, 2008 Share Posted February 22, 2008 We are talking about the Tanganyikan lamrologine here. Are you referring to the American tetracanthus? Bruce Link to comment Share on other sites More sharing options...
fishdance Posted February 23, 2008 Share Posted February 23, 2008 No, we are both talking about the same fish but the way of sexing is similar. Have a look at the tail spots for sexual dimorphism Link to comment Share on other sites More sharing options...
