introducing an adult

Question
hi there i have a 2 year old B/D and want to inroduce another one of the same age is it ok the tank is 5 ft long?

Answer
 Dragons are very territorial and will not like company in their territory at all.  Two males will fight till one is bleeding or dead.  An established female will not accept a male in her territory and will rarely accept another female, especially at this late an age.  An established male will accept a female, however his constant harassment to mate will stress her to illness and an early death.  So my advice is do not do it at all.
