What Kat2 has suggested is normally sound advice, but typically for larger in-ground plants. Young tissue culture plants tend to produce these small water suckers in some situations, they will grow, but may not do much, especially in a small pot as you have yours in.

If you are planning to make a serious attempt at fruiting your plant, I would advise removing this young sucker and any subsequent ones until it is a much larger plant, and potting your plant into the largest container you can manage, ideally at least 20-30gal. You want to focus resources on the main shoot, which will need all the help it can get to make it to fruiting.

Small water suckers can be separated and potted up (if removed properly) to propagate more plants, and in this way they will grow up to be fine normal plants, but if left on the mat they tend to lag behind and not perform as well in the end.
