How many in one tank?

[Bodom]

I will be setting up a 130G heavily planted tank with lots of hiding places, is it possible to keep a more than just a pair?

That's not much Info. The water volume is not as important as the footprint.
I'd take a look into the A. borelli group. I know of setups with up to 4 pairs of A. borellii "opal".
If the tank is structured correctly that could work.
