Ok from reading I'm getting the sence that aquariums arent good for cammies... thats what i have I get that screen ones are better but will a 40 g tank with screen not work.
It would definitely depend on the species. When you say aquarium, I'm taking it that you will be using a fish tank vertically and the screen being the door. This will work, but it will require fine tuning. Being the Temperature and Humidity. Of course the air can become stagnant in this type of cage, but I believe some people over worry about the amount of air getting into this type of cage. Everytime you open the cage door to feed, mist or even to interact with your chameleon. The air inside the cage gets replenish with fresh air, thus eliminating stagnant air. If your screen is located at the front of the enclosure, everytime you move pass it there will be air movement within. I have my velied chameleon inside this type of cage and they are all doing fine. My oldest velied is 2yrs 5mths old and was bred by myself. If you are really worried, set a fan on a timer to go off every hour for a few minutes. Just make sure the enclosure is big enough for your chameleon.
Incase you were refering to me, my uvb light is inside my enclosure.
Curious to where you read that any sort of cham does not need UVB light?
thank you for pointing that out ... i intend on getting her a uvb ...right now shes just got uva ...... for now i'm trying to get her nat light for a bit everyday.Really not trying to be rude, but the article you are siting is over 10 years old. The studies that are being done right now are not debating on whether UVB is required by chameleons, but how much is optimal. UVB is absolutely required. There is not a recent study that states that chameleons do not use a photochemical process to synthesize D3.
I cannot tell you how many chameleons and other diurnal lizards that have come into my clinic only supplemented with Calcium w/ D3 and no UVB. Not surprisingly, most of those cases revolve around secondary nutritional hyperparathyroidism (MBD)
I am troubled that misinformation is still floating around out there suggesting this point...
I live in ontario (canada for you usa folks lol) I've been dusting with Rep-cal calcium with vit d3 .... I've just been trying to take her out a bit each day to make up for not having the uvb light ...about 1/2hr ....well yesterday was the 1st time i just got her sat ...she's still adjusting. Today I was thinking i would take her out longer as it is supposed to be warm well hot to me lol it's 9am and it 19 out already! suppossed to go to 22!kellyspetparties...you said that you are taking your chameleon outside...and you say you are giving it calcium with D3....a word of caution....D3 from supplements can build up in the system and if your chameleon is outside for an appropriate length of time it likely doesn't need more D3. Are you dusting with a phosphorous-free calcium powder at all?
Here's an article about UV light transmission....
Regarding glass tanks...I live in Canada and the winters are quite cold and in the house its quite dry...so I started off MANY years ago using glass tanks with screen lids. This is done successfully in areas of Europe where the climate is somewhat like ours is. Some of them I even closed in part of the screen lid to help keep the humidity in. Using glass tanks with screen lids does not come without concerns...and I certainly don't recommend them being used in areas where the temperatures are hot...but in all the years I did that I never had a chameleon contract a URI or other problems that I could attribute to keeping them in glass cages. I kept C. chamaleons, veileds, panthers, rudis, Senegal's...and quite a few other species of chameleons in glass cages. Most lived long lives...even the WC's.
Quite a few years ago I switched to cages that had three sides and the floor glass and the door and lid screen. This makes it difficult to keep the temperature and humidity up in during the winter...and I hate putting the chameleon in the situation of having to sit under the basking light all (or almost all) day in order to keep warm and digest its food.
