It's a basal keiki and if I owned the plant, I would leave it to grow as it is and make a super display when all the spikes bloom.
The only types of keiki that I have removed are the ones that form on the actual spike. Then you wait until the roots are two or three inches long before you remove it. Sometimes the keiki can have trouble adapting to a new pot all on its own--try wrapping a bit of sphagnum around the bottom of the baby and spray daily. This will give it the benefits of more humidity and make the transfer less drastic for the new plantlet. Worked for me!!
