I wouldn't risk it craig, unless you think your bredli needs feeding up as this is more than likely what will happen in the future, regardless of what sex they are. Maybe if they were a diamond or carpet they would be okay and you could separate them at breeding age, but I think it would be sad to lose one or the other.
kind regards

just a bit of topic, I was at my herp meeting last night and a member that I previously sold 3, 6month old mountain dragons to, told me that two had died. Considering the work that went into raising this guys (they are extremely small and will only eat insects), I was quite dissapointed though offered to replace with some animals this breeding season.
He then proceeded to tell me that the remaining dragon was quite happy as he was sharing an enclosure with their water dragon. Imagine if you will, a pittbull sharing an enclosure with a rabbit and this is comparable to size difference/disposition of animals involved.
Although some people think that we only breed animals for the money involved, alot of us put our hearts into breeding a new species of animal, and can be pretty devastating when you sell an animal, only to have someone shrug off its demise.
