Hello! About a week ago, I got a new crested gecko, and recently, I’ve noticed that its stomach moves in and out quite noticeably. The movements are pretty big, almost like it’s taking deep breaths or letting out big sighs.
I’m not sure if this is normal or something I should be concerned about, especially since I’m still new to owning this gecko.
Has anyone else experienced this with their crested gecko? Is this normal breathing, or could it be a sign of something wrong?
Any advice would be greatly appreciated

So for the last 4 months I've had a female side blotched lizard chilling in my backyard. I set out a water bowl for her and some like terracotta tiles because google said she might like it. I don't feed her or anything, but she hangs around and she's super chill now that I think she realizes I fill up her water bowl. She used to live underneath the dog pooper scooper in the corner of my yard.

Well, about 2 weeks ago a new lizard was in her place under the pooper scooper and she's moved to under the grill about 10 feet away. I'm pretty sure the new lizard is a baby southern alligator lizard. I did some googling because I didn't know if they would hurt each other, and when the baby gets bigger there's a chance it could eat my side blotched lizard.

I love having the critters in the yard so I'm trying to figure out the best way to keep them happy but also like away from each other? I don't plan on directly interfering if wildlife does what it does, but if there's a way to maybe encourage them away from each other I'd like to do that.

So, I guess my question is whether there's a way to have them both live in the backyard without the alligator lizard maybe eating the other lizard when it's big enough? And if there is, how would you go about making it possible? I rent so I can't do any permanent changes, but my landlord is fine with me having the critters around and modifying things so long as it's not permanent. Thank you in advance!
