Iguanas and Fish

Question
I'm going to be building a huge cage for my iguana and a good size of the bottom is going to have water in it and I was wondering if I could have small fish in their or not...thank you

Answer
I am sure it could be done. Although I am not sure what type/species of fish you could put into the enclosure meaning tropical fish would need heat etc. Given that though I don't see an issue with it. I don't see the Iguana messing with the fish at all.
