Housing multiple lizards together?

[valhalha30]

What you ask is quite demanding honestly.
I would imagine you'd be ok with housing different types of geckos together, but really, I have no idea.

It's not a good idea to house more than 3 different types of anything together, especially since many reptiles are known to be cannibalistic. And if you have all males or all females of different species, there will be constant fighting (usually) in some cases, maybe not.

With the requirements you are asking for, well, there isn't much of anything to choose from. And to co-habitate in a 125 - 150 gal tank, and have to be under a foot long yet..... I can think of lizards that grow longer than a foot that can co-habitate decently, but not anything small..... except a colony of green/brown anoles or long tail lizards or small chameleons. BUT those are ONLY single species colonies.

I have a Cuban Anole/ Giant knight Anole and a Tokay Gecko, both male, in the same 55 gal tank, but both exceed being a foot long.
My Anole eats pinkies, which is meat... and so does my Tokay (sometimes, if he's in the mood)
What I have isn't exactly ideal, in most people's sense of keeping two different species seperated at all times.
They do fight, not often at all, but they do. Which is why you should do as I say, and not as I do. BUT if you REALLY want co-habitation, there are others who have the same lizards as I do in the same tank. You should keep A day-dweller with A night-dweller for peaceful co-habitation.
Otherwise, don't do it.
