Hi, Rachel:
>>i'm considering getting 3 of these. do they eat crickets just like the anoles do? they dont seem to be as agressive as eaters as the anoles are.
Yes, Long Tail Grass lizards do eat crickets like Anoles. But they are just as aggressive eaters as Anoles are, if not more so, since they tend to spend all of their time at the bottom of their tank, whereas Anoles like to stay at some point above the ground in their tank and when you put those live cricket(s) in the tank to feed them the crickets will at least at first be running along the bottom of the tank right where the Long Tail Grass lizards like to hang out and then WHAM! Another one bites the dust! 
Not that you said whether you're going to put the Long Tails in their own tank, but you should definitely consider doing that if you haven't already decided to do that. The reason I say that is because I tried to put a few Long Tail Grass lizards in my tank along with just a single Anole and well...it didn't work out well for the Long Tails. Although in my case I really didn't have a big enough tank either for as many lizards as I *thought*
I could put in my tank which only made it worse for all of the lizards in my tank. I, and my Long Tails, learned the hard way.
The common concensus amoung successful long-time Anole/Herp keepers (of which I am *not* one - I'm just offering my own personal recent first hand experience in the event that you have the same "human" idea *I* did) is that there should be at least 10 gallons of space for each and every lizard in a tank. Otherwise lizards will feel crowded which will cause them to feel stressed out and that can be very bad for lizards living in a captive environment since they cannot run off as they could do if they were living in the wild.
Hope that helps. Peace.
