NGTs or Campbelli is a daffodil yellow with black stripes that fade a bit with age. They are known to more fierce than the other types. Indos are more common and cost me a lot, lot less than a Ngt. Take your pick.
they where all really wide barred and had only 3 bars. all of them, they really looked like pulchers to me, but the guy sold them as 3 bar indos, so guess they are indos probably, but they where really nice you will see...
