OEBTs are a little harder to breed than most Tigers. They tend to take their time to adjust to any new things, food, substrate, tank etc. However once they feel comfortable, they will breed. Mine took ages before I saw a berried female.
For me its the Black Orange eyed Tigers I just cannot seem to get to breed...I have one huge male, yet never see it checking out any other females. I think I will have to buy some more outcross juvies to start up another tank just for them.
