housing different species of reptiles together

Question
is it possible to keep small iguana's and frilled dragons in the same tank ?

Answer
Hi Lee,
No, you cannot house any species together and many times, you can't even house the same species together...especially iguanas.  
Even as a baby, one iguana should never be in anything smaller than a 55 gallon tank..and he will out grow that by the time he is a year old, provided all the proper care is given.
Also, different species have different diseases many times.  These diseases may not be a threat to their own species, but can be deadly to other species.
In the case of iguanas and frilleds, their diets are different as is their temperature requirements.  Frilled dragons are also very aggressive toward other species.
If you need more care info on either species, let me know, especially on iguanas.
