friend for pet

Question
I have a green anole (the anole is female if that changes anything) and i was wondering what other reptiles could go in the tank with her without causing stress. P.S. what size tank would they need?

         Thank-you

Answer
It's best NOT to keep reptiles of different species in the same enclosure.  However, I have seen green anoles kept with house geckos with little interaction (and thus, little stress).  An extremely large, heavily planted enclosure would be needed.  Since house geckos are nocturnal, the two animals can avoid one another easily.  House geckos are also an introduced species in the green anole's native range, and they're often collected from the same areas.

I would recommend nothing smaller than a 30 gallon enclosure, if housing the two species.  If you're keeping a trio of green anoles, you could go with a 20 gallon tall.

New animals should be quarantined for 3 months to ensure they are healthy and free of disease before introducing them to existing animals.

Green anoles are considered beginner reptiles, but in reality they are NOT.  This is because they are invariably wild-caught, which means they have parasites.  For long term health, these need to be treated by a vet and eliminated.  (Just as with the free puppy, there's no such thing as a free--or cheap--reptile).  
Green anoles require UVB light, controlled heat (daytime temps of 80F with a 90F basking spot), plenty of cover and climbing branches, and a humidity around 80%.  Water should be provided by spraying twice a day.

Insects must be dusted with a calcium powder (use a vitamin supplement once a week).  They may also appreciate Repashy crested gecko diet served in a small portion cup.

Reptiles of virtually all species prefer to be solitary, so in terms of a 'friend', your anole would rather not.  If you really want to keep a different species of reptile, your best option (and the best option for your anole) is to get a separate enclosure for the new animal.
