some can if identical in growth rate, some of other can be more aggressive growing and can overtake others as well.

Normal.
The stronger will take over the rock. That doesn't mean the weaker will be 100% gone.
Most times most species grow together without any problems.
main thing is to keep all params stable and within the acceptable ranges for most of what you've got. without predators.
