Hi. I am in need of some help and advice . I have posted this plea on the Aussie gecko forum also , but have had no reply, so, as I am getting concerned, I am posting here too. Two of my strophurus spinigerus females have begun fighting. I've four in an exoterra tall medium enclosure, wth plenty of branches and hides. They are all female, and all have been together for around 18 mths. I've had them for around 8 mths. There is a lot of vocalisations, grabbing eachother ,and knocking one another off the branches. I'm wondering if it a need to mate thing? Shall I get a male? Are they hormonal,... Now they are nearly two yrs old? I worry that they'll hurt each other...... I am puzzled because they were no signs of aggression before three weeks ago. I would appreciate any insights, advice, comments, from anyone . thank you .
