...I've heard the opposite actually. Most breeders I've talked to say that to reduce fighting and acclamation time, you should only introduce them once and keep them together year round in a large enough tank - 2 in a 20L, 4 in a 40 breeder, etc to reduce 'arguments'.

Then again, I have yet to breed them as well. Your best bet would be to contact an experienced breeder online or at a show. Geckosunlimited forums can be a good source also.
