I keep reptiles because I am passionate about them. My choice to use reptiles in my capstone isn't for an easy A or a ribbon or any of that. I am only using them because I am really passionate about them.I realize that cohabbing is typically bad. In most species it can cause injuries, disease, or death of one or more of the animals. However I truly believe these animals will do great together. I would like to know if any here has owned either of these species. No one has said, "oh well my pink tongue skink is really aggressive" or "my crestie is really aggressive". Everyone is just asking how I can be so confident about it when I have never owned either species. It really seems like everyone is just talking like they know what they are talking about without citing their own experience. If you have found any issues with either species please just tell me. I know that no matter how docile a species is there will always be a few that aren't, but I can talk to the breeders about their temperaments, and see how they behave. Of course there might be a few that lie just to get a sale, but I'm in contact with a reptile keeper with years of experience that has been going to this expo for a long time now. They can tell me who to avoid, and who to trust. And yes I have talked to people that have owned crested geckos. Everyone goes on about how easy they are to keep, and how docile they are. I have brought up breeding multiple times because it shows how compatible they are. If these two species can get along well enough to breed without issue that says something. The adults and babies of both species got along well enough, and if that doesn't make you think about it more openly I don't know what will. Yes they had more space, but I won't have nearly as many in one enclosure. And please don't talk to me like I have no care for their well being. I'm not soulless. I wouldn't even consider doing this if I found any evidence of there being even occasional cases of violence between these 2. Even when in sub par conditions they tend to do just fine. The absolute worst case scenario is they live fine for years, I'm off to college and for whatever reason I can't keep them until I finish. All of the sudden they start fighting. What do I tell the person keeping them for me to do? A wood barrier between the 2 of them until I can send money for 2 individual cages. I'm already starting to save up money for that should it ever happen. I have thought about this. And I'm very confident that the temps will be fine. I have a light for my ball python that gets to 120. And don't worry her basking spot never reaches over 100 degrees it's typically around 90-95. Not even a foot away i have a thermometer that reads 75 degrees. There's no doubt in my mind the crestie will be able to get away from the skink's heat source all day and night. So please don't repeat yourselves because I'm starting to get sick of doing it myself. If you have owned either of these species, and can give me some advice from your own experience I'd love to hear it. But for the rest of you that have not owned one or both of these species please stop replying. The one thing is I haven't been able to contact anyone with experience with a pink tongue, but I've been working on it and I will continue to. Thank you for your criticism. I have taken into consideration, but I am yet to find any hard evidence to change my mind.
