Please ID this? Tiny polyps growing on the rock

[Deisler]

Hi,

 

Today I knocked my big coral off and found a tiny group of polyps hiding beneath it. They look like an individual group of polyps that are by themselves, directly anchored on the rock. 

 

Each polyp is about 1mm in size, so tiny. It does not appear to have any strong colour.

 

Does anyone know what it is and if I need to worry about it?

 

Image attached - sorry please ignore the hair algae at the foreground.

 

Cheers

looks like Kenya Tree polyps to me.
