House mates

Would it be alright to house a cuban knight anole and an iguana together? they are both three or four years old. Would they fight?

The Iguana would eat the anole! Just kidding, but You should not risk it just incase they dont co-operate together and they get hurt badly!:(

I know this is an old post, but... I have a male Cuban who is about a year old, and he co-exists with a male Tokay gecko who is also about a year old. Most of the time they are fine, since the anole is mostly active at day and the tokay is active at night... but having said that... sometimes the gecko is active during the day, or Buggy, my CKA, decides to pick a fight with the tokay in it's hide-hole.... so there is the occasional fight, but it's never too serious and typically they don't even socialize with eachother.
Both are similar in size to eachother... and both can defend itself well.... with any Cuban, it's hard to find a tank-mate. I found that the Tokay gecko was most compatible, unless you put in a female Cuban VERY CLOSE to the size as the male Cuban.
