Hi to all. I need some expert advice and/or any input regarding the following : I have four female strophurus spinigerus, they have always been housed together, and all get along extremely well. They are approaching two years of age. In the last few weeks, two in particular have begun fighting. Not really biting each other, as such, but lots of grabbing of neck, back, feet..... They frequently knock eachother of the branches. It is a large, tall exoterra enclosure, with lots of branches and hides. I was wondering if they are seeking to mate? Are they hormonal?? Shall I get a male? Would that help? Any views would be greatly appreciated. Thanks fellow gecko lovers!!!
