Small Black bump on Skeleton of Indo/Cynarina

[noober]

Hi guys, just got my first meaty coral. I'm not sure if it's a Cynarina or an Indo. But I noticed there is a small black bump on the skeleton. No signs of color.

It's only visible when I feed it and it recedes, otherwise it has been completely healthy and color has been amazing.

Is it a baby polyp or a disease or some sort of critter? If it's a baby polyp what am I supposed to do to maximize its survivability?

Here's a picture of it when's it's about 80% out. Maybe you guys could help me identify it too.

Cynarina. The indophyllias in the hobby are actually cynarina macassarensis.
