Coral health in small space

[Jatchetto]

Hey guys sorry if this has already had a bunch of post if, so a link would be great. I tried looking maybe i was searching the wrong key terms but regardless i was wondering about coral spacing. Ive added a bubble to the tank and it looks great but filled/ is filling the space very quickly. I was wondering if it runs out of space will the coral grow out the side or will it grow into the rock and pop the bubbles? Also does limiting the space affect the overall health of the coral and should i try to move it? Any advice appreciated thank you and if you have some corals in tight spaces or filled there area lets see them!
