Ok so based on that, there is a slight concern imo - the 7% might be too high for a crestie, depending on how far away he is from the light (needs to be at least 12 inches above his basking spot through mesh to give correct readings for cresties (UVI 1 ±). They’ve made a shadedweller specifically for arboreal geckos like cresties that’ll give you proper readings between 2-6 inches through mesh - idk how far away he is from the light though, and how well he climbs, but I figured that could be a problem - theoretically d3 overdosing could cause similar symptoms to MBD, but from my understanding while you don’t need to supplement with d3 with proper UV, doing it still is very very unlikely to cause problems, you’d have to be giving insanely high amounts. Based on that and what you’ve explained I think it’s more likely that he’s either kind of growing into his deformities which makes them appear worse, or that something is wrong on the inside. That being said, eating and everything passing through is a very good sign, as long as that’s happening, he gets around ok, and he isn’t showing signs of being in pain, I wouldn’t be too worried
Ofc ofc. I don’t give the D3 constantly, as I got calcium without it since I got the Reptivite WITH D3, I didn’t wanna double whammy him there.
As for his light I have a muscle rack with all of my enclosures on it. I have the light fastened to the top of the shelf and away from the immediate top of his enclosure, I would say there is roughly 10 inches between them. He climbs moderately well but usually always settles himself into the most… awkward looking positions. His tail is also something of concern to me, he seems to have a lot more control over it than any other gecko I’ve had. He can fully curl it 360 degrees around branches ect ect. Reminds me of an opossum!
I’ll look into putting some more distance between his light and him. I’ll just have to break down my shelf again and put it up a few rungs higher.
that light distance should be fine. as long as it isn’t closer than that it should be fine.
Yeah that distance should be fine as long as he isn’t sitting directly underneath the mesh 24/7; the 12 inches is from the light to the gecko’s back in what is intended to be the basking spot (: Maybe the tail-control is due to him adapting to his disability?
That poor lil fella.
I was hopefully that it wouldn’t get worse but it did 
Has he been seen by a vet?
You’re doing so good with him! If he’s acting like a typical gecko, showing no signs of very inhibited behavior, then I’d feel he has a good quality of life and it’s worth keeping him, until that is no longer the case. I’m glad he doesn’t seem to be in pain.
New update. Honestly I didn’t expect so many people to be interested in him!
Quasi has been seen by a vet but I will say the vet around here is not the greatest. I work for a large retail chain pet store and there is only one exotic vet in the area, however, he is also like ten thousand years old and misdiagnoses frequently… We had a lot of tortoises come into the store with tortoise herpes and he said they just had a vitamin deficiency… necropsy proved otherwise. ANYWAYS, he basically said what most of you are saying. Monitor quality of life and if he begins to lose interest in doing your average gecko activities then it’s likely time to euthanize.
BUT, I am here to report he hasn’t done that. He skitters around and now he does the signature gecko plop onto the side of his enclosure all throughout the night. He completely cleans his bowls of MRP too. He’s still been pooping great, they aren’t runny or discolored and he passes urates still with no problem. Sheds great too, recently he got some stuck on his toes though. I had surgery and was out of my house for a week and my mom was responsible for him. I’m working on getting the remaining bits off. He’s finally growing a bit too! He is now roughly 8 - 9 months old.

Thank you so much for the update on sweet little Quasi! He is the cutest little thing ever! 
You have given him such a wonderful quality of life but at the same time I know he has put many smiles on your face as well! 
No matter what happens from here on, you have done what you set out to do and that’s to save Quasi and give him a great life! That’s a job well done! 
Have you any updates on sweet little Quasi? He’s been so fortunate to have found himself in your care.
Yes! Still doing very well, I caught a really good picture of him gripping on my thumb last week that I’ll try to upload. Still an avid eater, pooper, and finger painter. I am hesitant to move him into anything bigger than a very large critter keeper because his balance skills are sometimes lacking, more so than the usual crested, but in time I may be swayed.
If I’m entirely honest, I didn’t expect him to survive this long. It’s been nearly a year and he’s quadrupled in size-- something I find hard to achieve even in my normal cresties. That first year of growth I feel like always goes so slow… but with him he kinda skyrocketed.
On that note, I have the fear that he actually may be a she. It’s hard to tell with the angle his deformity makes his backend sit, but… if Quasi is female I fear that becoming egg bound might spell the end. Poop comes easily but I’m unsure if an egg would be able to pass through.
Thank you for the update. How unexpected and wondrous that Quasi is managing so extraordinarily well! You’ve clearly been an absolutely star quality keeper, @nygma. He (I’m sticking with that hopeful gender in this case) was the luckiest gecko in town to have connected with you.
I have genuinely no idea, so if this is a dumb question, forgive me. But is there any way to prevent female cresties from laying infertile eggs? Like, do certain environmental conditions trigger their reproductive season and avoiding those triggers could avoid egg production altogether?
I just know for goldfish you can breed them whenever you want by using food and light/temp to trick them into thinking spring breeding season is here, and I’m wondering if the reverse is possible (obvi cresties aren’t fish, but same concept).
Thank you for documenting Quasi’s story. Very articulate and whitty in some parts that shows your positivity!
Myself and my fiancé are brand new to breeding and unexpectedly have recieved several underweight, young gravid females 
. Thankfully the breeder is getting out, I will whistleblow if they come back. And my biggest fear (many sleepless nights) is these babies struggling because of poor care by the breeder. Although the future is never written, of course. It is a relief to know that even with the worst start in life, dedicated care can give a baby like this a good life, no matter how long. I sincerely hope Quasi is a he 
and so the rest of the life you have so compassionately given him, is as easy as possible for the both of you. Absolute best wishes, for you and all your animals .
Photo dump! I tried to get him from every angle, including his weird little tail gripping.
