I just realized the sand part was directed at me. I'm kind of surprised, because I never said not to use sand, just that calci-type sands were better.
Anyway, I'm born and raised in Miami, so there's no need to tell me that most of Florida is sand, although it's not really that way where I live. And although they don't have processed calcium sand in the wild, our sea-shell white sand isn't the same as the builder's sand and playground sand people use, either. But that is not the point. The point is that the purpose of captivity is to keep animals under better conditions than they would be in the wild. Just like they have plenty of toxic plants they live with in nature, but most people wouldn't purposely add a toxic plant to a vivarium even if the animals don't consume it, just as a safeguard.
Also, I'm not positive that calcium sand is or isn't sometimes natural. The product I use comes from Ft. Pierce (the company is really in Miami) and it's a fine grade sand that says 100% natural. Now, that would never make me assume that it actually is, or that it's collected from the outdoors, but the product that this company makes are based on natural products, such as crushed coral and natural florida beach sand. I mean, the calcium sand is obviously somewhat processed, but I still feel it's safer than regular sand or soil that these anoles do encounter in nature. And that assumption is based without my knowing how often anoles injest too much substrate and die of impaction, but I'm going to just try and be safe with all my reptiles.
Anyway, I doubt this will be read and I'm sorry it reads so terribly if it is, but I just had to clear up the whole issue. I don't think it's wrong to keep anoles on sand, but I just don't think it's fool proof enough, especially not for beginners, so that's my point!
