I Am Not Sure What I Have Here

Question

I have a cactus that pops out flowers when it is happy and moisturized. With the current rains, I have had as many as 13 flowers. This time, I had 6. Normally they wilt and fall off however one wilted and left me a surprise. As you can see in the photo attached, I have 1 new flower growing and below is the remnants of a flower still hanging on a red arm. Am I going to have a red arm?

No, but you might have a fruit or seedpod! Continue to care for it, and you may have some seeds later. This looks like Hylocereus trigonus. Cacti can be hard to pin down, though.
