Hi pdx_karina and welcome to the board of friendly 'naner folks!
I am pretty sure and I agree with Chong, it's a
SDC. Lovely plant you have there! I have a couple of them under the full tropical sun in the ground and they are very undemanding little fellas. I feed them weekly with pellets made from sterilized chicken dung. If your mother plant is well fed, the pup can be left as it is unless you want it to have its own space. Best is to let it get bigger before you separate it. Since it is a compact growing cultivar, they can be left together till the pup is 1/3 mommy's size. These guys really love water. All the best and do keep us posted of it's progress.
