Hey, I have a Giant Day Gecko, who is almost eight months old, we bought them from a reptile store. We have never sexed our Gecko, so we don't know what gender the Gecko is, it doesn't matter to us. we have only have one gecko set up in 18x18x24 tank, we are going to get a bigger tank in the a few months for more space. We have a live vivarium set up. Our Gecko is about 6 1/2 inches in size, we have called the gecko Fred, this is our first gecko of any time, so we are new to this and trying to make sure that everything we do is correct. Up until Monday Fred has been acting happy and normal, and Fred seemed normal Monday morning. I wasn't witness to this, but my boyfriend was, he watched Fred eat what looked like a white/yellowish sticky flatten mash-mellow that was stuck to the side of the tank, it didn't look like Fred's poop. We haven't seen anything like it before, and nothing in the tank should have put it there. Apparently Fred licked it a few times and then just ate it. Afterwards we noticed that Fred looked really skinny, like all the fat was sucked out of the lower part of the abdominal near the rear legs. Fred seem okay for the rest of the day, however when I was taking out the water bowl out to put fresh in, Fred got out (for less than two minutes). Not far only on the light on the tank (NOT THE HOT LIGHT, onto the box for the light which gives natural light). We quickly got Fred into the tank using a plastic box, so obviously Fred panicked a little and got stressed. We are still letting Fred get use to us so we haven't actually physically handled him/her yet. Fred spent the rest of the day at the back of the tank, as expected. The following day Fred didn't seem active at all, staying at the back, not really interested in food or anything. Drinking more than normal. Fred shredded their skin,usually they eat it but didn't. After doing so became a little more active right before the time the light usually goes off. Today Fred hasn't really improved much, has eat a little more but barely at all, has moved around a little more but again not much. I can't tell if Fred has put any weight on yet, but they still aren't acting themselves at all, I'm really worried, I'm not experienced with Geckos and I want to make sure that everything is okay, we don't want to stress the gecko out any more than what they haven't already been through. I've contacted a reptile place over the phone for advice and they said that it seems like Fred is a girl and has probably laid an egg but it's unusual for females to eat the eggs and that Fred should put the weight on in a couple days. I just want to make sure that Fred is okay, The only thing that has been different to normal in the past week is we gave Fred some tropical fruit mix-ins Mango, Fred wasn't really fused with it, and didn't really bother with eating it. I was wondering if anyone else has experienced anything like this with their gecko, I'm really worried, I don't want to cause any more stress to Fred, I'm going to give it a couple more days and if Fred hasn't improved in weight and become more active then I'm going to take them to vets. Fred loves crickets but is completely un-bothered by them at the moment, just sits looking darker than normal towards the back of the tank. Any one that could give advice or information, it would be really appreciated.
