Jack russell terrior twins always fighting with each other

We have two jack russell terriers the same age but from different litters. Both were acquired at the same time from the same breeder. Both male and approximately one and a half yrs old. Both have been neutered. They have been aggressive toward each other repeatedly and have even drawn blood from each other because of the fighting. Its kinda bizarre really. They cant stand to be separated from each other but when together, one is always picking on the other (growling, and poking at him with his snout - we call this the chicken dance ;) Sometimes the growling turns into full-on fighting.
any ideas of what is going on here and what we could do to reduce this? Obviously play for dominance and or jealousy of our attention could be at play.
