i woke up this morning, and looked into the gecko's viv and the moist hide, which i have made out of a ice cream tub with some kitchen roll was full of the reptile sand that covers the ground. I am not sure what this means, i have left the moist hide like it is for now, which is not moist and full of sand. I have a pair of geckos,definitely male and female but we were told that they were unlikely to breed, because they have been a pair all their lives, they are around 5 years of age, and when we bought them we were told that they were sub adults, but in fact they were at least 4, which we didn't realize until after wards. The geckos are not interested in each other what so ever, and i have never seen ANY interaction between both of them, this is why i doubt she is pregnant, but what does the moist hide full of sand mean? I have looked at her and she doesn't look pregnant, well from what i can see anyway. Do i need to buy an incubator? Thanks if you can help!! X
