mountain horned dragons

Question
i have 2 mountain horned dragons in a large aquaim. what othe creatures can be housed with them

Answer
 Reptiles are nortoriously territorial.  And unless you have a habitat like a modern zoo, it is never a good idea to mix species.  So many have different requirements for heat, light, food, water, humidity, and there is also the issue of parasites naturally found in the gut.  Also never house different sizes because one species could fall prey to the other.
