The breeder I've been talking to has varadero and leuc tads right now and I'm assuming if I were to get a pair they would likely be siblings, and unsexable. It would be a roll of the dice if they were male and female. I was just curious what the possible issues could arise IF they were to breed.

That's going to be awhile down the road before I purchase darts. I just want to make sure I know all that I can before that day comes around.
