No, i don't think it will. A regular misting once a day should do it. I have a Under Tank Heater under my pacman tank and it dries it out no more than a regular bulb.

So you are going to go with the one you WANT to hear. I get it. How about the more room the better? And I get that you built this and you want to make it work. I'm saying Plexi is expensive and you could probably get a used 29 gallon tank for the same price off craigs list AND give them more room.

And you are still going to have some issues... In order for them to receive UVB light it can't be filtered through screen smaller than 1/4". if you screen on the top of the tank is 1/4" or larger, the anoles will get out, especially if you have the screen going all the way to the top as added climbing space... just something else to think about.

I'd shoot for around 70% humidity. It can go up to 80% or down to 60%, so 70's nice and safe. Ultimately you have to consider that they're native to the southeastern US, from the Carolinas to Florida to eastern Texas. Mimic those climates and you'll be fine.

If your habitat is 20 gallons I'd stick with two anoles. Unless you're prepared to breed them, get two females. Three is pushing it, and anything over that is definitely overcrowded. The presence of a male will often stress out females a bit, and DEFINITELY stress out other males.

As for the top, you could have finer mesh for most of it, but keep the 1/4 inch screen under the UVB light. Thus, the area of 1/4 inch screen will depend on whether you go with a mercury vapor light or a fluorescent. With only 20 gallons, I'd probably go with a fluorescent or two, plus a heat lamp for basking.

UTHs are good for frogs, snakes, and some geckos, but for diurnal sun-bathing reptiles, like iguanas, crocodilians, anoles, turtles, etc, a heat source from above is better. Combined with a UVB light, it mimics the sun.

I was always under the assumption uvb would go through even a 1/8" sometimes smaller.
I personaly think a twenty tall would adequetly house up to three green anoles. With all these isssues it's tempting to buy plexi and silicone and build my own tank. the problem I face is that there's a certain sized space, and many tanks would not fit. a ten or a twenty tall fit perfectly. But im not as sure about a 29.

That assumption would be false. Ultraviolet wavelengths are very short and can't penetrate in the same way that visible light can. Window glass, as an example, blocks over 90% of UV rays shorter than 300 nanometers, which includes all UVB and even some UVA. A fine mesh will do similar. It will let some UVB through, but not enough, especially coming from a UVB lightbulb. Compared to the sun, UVB bulbs are really weak, even the best of them. A fluorescent UVB will only be able to project the UV rays about 10-12 inches at best before they start to fizzle out, and that's without anything in the way to filter it.

I'd still stick to two female anoles. There's no sense in adding more when less will always be better.

Actually 1/8 inch openings aren't too bad unless it is some really heavy wire.
Anything smaller than that is defeating the purpose of the lights.

Well. The Mesh Tank Topper has been placed on my Gecko's enclosure, I think if you could talk he'd thank me for the room. I was at petco today, and they had a out of box 29 gallon reptile tank, with screen top. They sold it to me as a 20 high aquarium, so I paid about 40 bucks for it. (reguraly 80-90) Not a bad deal in my eyes. i moved the gecko's tank, and stand to where the frog tank was, and once I get a stand or piece of furniture suitable I will put the 29 where I had the gecko's tank. So quite a bit more elbow room for whatever I choose to occupy the tank. I'm almost leaning towards frogs again with the all glass tank, but agree that Red Eyed tree frogs are not the best choice for starting frogs. I would really love to get Two Green Anoles, And Two Green Tree Frogs. I have heard this is possible, so long as you make sure the size is right. Any Opinions on it? I know it will be a bit of a challange, Anyone have any personal opinion on It?

you cannot house green anoles and green tree frogs together. End of story.

I've seen it done before, and successfully. The frogs cannot be big enough to eat the anole's, and likewise need a space they can get away from the anole's. Im just not sure the tank I have is big enough to accomodate the special considerations. Now australian green tree frogs and anole's, say bye bye mr anole. green tree frogs get about 2"-2 1/2" large. An adult anole can reach about 7-9 inches long.
An old friend of mine had two green anole's, and three green tree frogs in a tank, granted the tank was I beleive a 40 breeder, but while the animals were not the best of friends there were also no signifigant problems between them. they each tended to favor a certain "level" of the tank. last I saw they were still all there
