” yes it would be inhumane to keep any uro in a 10g for the rest of it's life, but in a temorary situation as this, I agree with the original poster, assuming that the uro is very small. As long as there primary needs are met, there is always room for upgrading enclosures.”
My point is not based on the size of the animal but the size in which a ‘proper’ gradient can be achieved. Again, I am referring to temperature range and space.
It is my opinion that this cannot be accomplished correctly in a 10-gallon for a species which requires a higher basking spot and gradient than most other reptiles kept in captivity.
” I do not believe to say that if a hobbyist wishes to keep a small uro in a 10 or even 15 gal. is not responsible or right in assuming so. No person can pass the judgement unless they've personally seen the husbantry.
I do not need to physically see the husbandry when I have had years of experience in setting up dozens of enclosures for dozens of uromastyx. Maybe my standards are higher than everyone else when it comes to the term proper but I will adamantly defend my opinion that a 10-gallon is irresponsible when it comes to any size uromastyx.
” But regardless, he came to a forum to learn like the rest of us?? Isn't that what presumeably (sp) a forum is for?
Yes, that is what a forum is for but in my experience, those that post for help and ignore the suggestions they receive to start citing that they work at a pet store and are not new to the species are usually those that do very little learning on the forums.
” But consider this: Aquarists, such as myself, have quarentine tanks on seperate systems from the main one, and believe it or not, these quarentine tanks for fish are typically no more than 20 gallons - 29 tops when the main system is say a 75 gallon. An aquarists quarentine tank is really no different than that of a herp.”
I will agree when I need to achieve the same type of basking spot and high gradient with my fish as I do with my reptiles. 
”We all have our preferences but I find it much easier to study and watch over a sick animal in a smaller environment versus a 4 foot enclosure where stress of the space of a smaller creature can possibly increase problems.”
If I were a betting person and had to place a bet on which would stress a sick or convalescing uromastyx more- an enclosure that is too small or an enclosure that is too large (not such a thing in my book), I would bet on the small enclosure.
I can understand the idea of a quarantine enclosure being smaller but it is my belief that it should be large enough to allow for a proper gradient and basking spot and this does not include 10-gallon fish tanks.
”My opinion of larger enclosures with small animals, and the stress issue, can be rooted to baby ball pythons who are notorously shy animals. However, I suppose filling up the space with plenty of hiding places works too.”
It is my direct experience that young and/or small uromastyx are not stressed in large enclosures. Rather than write it all out again, here is a quote from my website regarding uromastyx hatchlings and large enclosures. The quote addresses a couple of the claims that have been made about larger enclosures being stressful or causing problems with feeding for hatchlings.
"I have read reports of larger enclosures being ‘dangerous’ for hatchlings due to younger animals being overwhelmed and stressed by the large space or that the hatchlings may not be able to find food. I personally find this preposterous considering that in nature these animals are not confined to small enclosures with set parameters once they exit their burrow. Granted, most hatchlings stay in close proximity to the burrow immediately after hatching but this is primarily due to predation. Close proximity in nature is a couple of meters in all directions so I do not think we need to concern ourselves with offering too much ‘space’ in captivity. My uromastyx hatchlings go directly into 4 or 6-foot enclosures from the incubator. My geyri (5-7 grams) have no problem utilizing the entire 4-foot enclosure the day after hatching and I have not had one hatchling that was not able to find food because of being placed in a 4 or 6-foot enclosure."
